I am completely new to AS3, and am trying to learn the basics, but have been having issues with what I think should be a simple command. I need to have two frames, the first one with a simple button that when clicked loads frame two and on frame two a seperate button that when clicked loads frame one.
When I try using the following type of event handler, i can link from frame 1 to 2, but not back and get an error message:
(TypeError: Error #1009: Cannot access a property or method of a null object reference.

I understand how to create simple buttons as reuseable classes, but how could you create a next button that does something similar to the AS2 "goto and stop nextframe", and a back button that does something similar to the AS2 "go to and stop previous frame".On each frame that the user navigates to, is a movie clip, within that movie clip is then another button with a go to and play "Frame Label" action required, that navigates within the movieclip to a specific frame.

I am All Programmer when it comes to anything including flash. I got into making games not to long ago and some people use frames to navigate from the main menu to the game screen and so on (which I have no idea how to do). and some people encapsulate the game inside of a class and call it from the document class and add and remove it when please

I'd like to have a function that tells a MovieClip to go to a specific frame and then in this frame, look for a scpecific tag in an XML file, based on the frame's label, and then take some text (a bunch of actually) that is in the XML node and put it on a TextField.
For example, clicking on a "Next Frame" button it will go to the next frame (which has a label "intro") of the movieclip and then search "content.xml" for the tag that contains the attribute name equal to "intro" and then put the content of the ".@TEXT" node into an empty TextField that is already positioned in this "intro" frame. Am I obligated to have the code in this specfic frame? I'm doing it because if I have too much text within textfields in an FLA file it becomes incredibly lagged and therefore impossible to work.
I've tried to use the event ENTER.FRAME to do that but it rendered the
SWF lagged and consomming way too much memory.

OK so I have a flash project consisting of four keyframes with "stop()" on the first frame so that it doesn't play through.I have "next" and "back" buttons on each keyframe so that you can navigate between the frames.However, I have a problem where the buttons seem to remember the frame they were on and they skip keyframes when navigating back and forth.Example:I'm on keyframe 2 and press the "next button" and it takes me to keyframe 3.I'm now on keyframe 3 and I press the "back button" and it takes me back to keyframe 2.I'm back on keyframe 2 and I press the "next button" and it takes me to keyframe 4???I have basic code on each keyframe.On keyframe 2 I have this code:
Code:
next_btn.addEventListener(MouseEvent.CLICK, nextone);
function nextone(event:MouseEvent):void

I'm using flash for the first time to create my graphic design portfolio and I'm having trouble keeping the file size small, and can reduce it by (hopefully) doing the following:
My resume has a lot of classic tweens with alpha channels (to create fadein/fadeout effects) and as of right now, I need to create a separate layer of fadein, fadeout for each transition. IE: My resume to portfolio page needs one 20-frame transition, my portfolio page to resume needs a 20-frame transition, my 2nd page of my portfolio page to my biography needs a 20-frame transition, etc. It's getting out of hand.
I could easily remedy this by using a lot of separate fadeins fadeouts and then coding buttons to navigate from, say, frames 120-130 (resume fadeout) then go to frame 160-170 (biography fadein), then navigate to a static page. I'm not sure if this is possible, as my buttons would have to change functions each frame.
Another possible way is that currently for each button I have different layers in order to direct the button to different frames, and have placing hem in the same spot. I'm wondering if there's any way to have buttons go to separate frames on different frames, if you get what I mean (on frame 120 it'll go to 130, on frame 150 it'll go to 160 but still be the same button". Right now each button is coded with on release gotoandplay <frame>.

I have a show I'm trying to create, I need to put the navigation buttons on different places on each frame due to content.
Code:
on (release) {
prevFrame();
}
or
Code:
on (release) {
nextFrame();
}
and
Code:
on (release){
gotoAndplay("Scene1")}
I can get the symbols that I'm using as buttons to work in the first and second frame, but they will not work after that. Each frame has a
Code:
stop ();
Action applied to it.
I have tried: copy and pasting the same symbol into multiple frames, dragging new symbols into multiple frames, creating folders for each frame and dragging new symbols into those folders then onto a frame, and I'm still not having luck. This presentation is set up to run in Flash 9 with Bottom up loading order and ASP2

I want to play 2 separate labels in a movie clip in any order when clicking a button that lives inside that movie clip.
Here's what I have on the button:
on (release) {
gotoAndPlay("location_rev");
gotoAndPlay("residences");
}
Currently, the playhead is going to "residences," entirely skipping "location_rev." I've thought of an if statement to ask Flash to play "residences" when arriving at the end of "location_rev," but I'm not entirely sure how to go about that.

I have some dynamic text fields in a frame called ExerciseFrame (which contain different random numbers, texts, ... and other variables.) When I navigate to another frame called helpFrame and back to the exerciseFrame again, all variables and text fields and other random numbers,... are reset. I mean text fields which contained many data in them becomes empty! I do navigation by a button in exerciseFrame with a simple
eventListener( gotoAndStop("helpFrame");
And in helpFrame another button with this code
(gotoAndStop("exerciseFrame");
How can I keep the state the whole exerciseFrame unchanged when navigating away from it and back to it again? version: AS3 - Flash CS4

I've got an interesting issue with the actionscript in my file. I've created a slide show with 27 labeled frames - they've been labeled "frame 1", "frame 2", "frame 3", etc... My issue is the first time everything works perfectly, if you hit next or previous. It goes to the correct frame. On the last frame if you click next it should take you back to "frame 1" and basically loop through all the frames again if you keep pressing next. The problem is it goes back to frame 1, and then next doesn't work on this frame. I don't understand what's going on considering the first time around - these frames work perfectly.Here's the code on frame 1:

this is the scenario...
main timeline---> two movieclips
in one of the movieclips (which is navBar_mc) i have my buttons in a drop down menu. so it is one level deep i am guessing.in the other movieclip (content_mc) i have the content that is to be manipulated by pressing the buttons.what would the code look like to target the content? i know i have to go up a level and then address the sibling mc, but when my code looks like this....
-----same---up-----over------------down-------------target
-------|-------|-------|-----------------|-------------------|
------this.parent.content_mc.nestedcontent.nestedcontent
it finds the main timeline ok, but when i address the sibling mc on the same level, it gets lost.

I would like to start out by saying I am very new at this and am working on a portfolio website in flash CS4 and currentlyhrough the tutorials over at Now my problem is In the portfolio section I want a preview of the pics like a thumbnail on the bottom with a scroll bar to scroll through them all, but at the same time I would like to have buttons to navigate through these photos at the same time. I have got it to work, the only problem is let say i'm using the buttons to navigate through but then stop and go to the scroll bar on the bottom and click on one three of four pictures in front of where I left off, The image loads and everything is fine but when I go back to the buttons it continues off from where it last left off not where I clicked on the scroll bar.Here is the code that I currently have:
myscrollpane.source=allthumbnails;
//load the thumbnails...

I have a nested movie 1 layer down from main stage that has several navigation buttons that move to different main stage labeled frames. I get an 1120 error because I am somehow not calling them out on the script. I have named the instances..so that's not the problem. I think I just need to somehow direct the script to the nested location. If I move the buttons to the main stage I get no errors and it all works perfectly.
