ActionScript 2.0 :: External SWF Files - Movie Does N0t Go To The Next Scene?

I have each page broken out into scenes. Intro, Step1-19, and outro. Here is what i have in scene 2. Keep in mind the swf file i am calling was generated with Macromedia Captivate and i dont have a way of editing through flash that I am aware of. I need some time of code that tells scene 2 to go to scene 3 when the external swf file is done playing at 737 frames. Ok here is what i have: all on one frame

1. stop action

2. a label for navigation purposes

3. preloader action:

var myMCL:MovieClipLoader = new MovieClipLoader();
var myListener:Object = new Object();
myMCL.addListener(myListener);[code]....

Problem 1. I am using actionscript to call the external swf file. I have a preloader that is working somewhat. It preloads the movie with a bar and when it reaches around 60%-70% it starts playing the movie too soon and the bar doesnt go away till it is full. So you see the movie playing with the bar still loading for a bried time.

Problem 2 (bigger problem that 1). After the movie plays it stops and doesnt go to the next scene because I had to put a stop action on the first frame for the preloader to work. So it plays the external file in the container but doesnt move on to the next frame or scene.

I had a friend try this approach and got an error: Make a MC that has an action script that says..

onClipEvent(enterFrame)
{
if (_root.step2_container._currentframe >= 737)[code]....

That sounds like logical but isnt working. The error I am getting is: **Error** Symbol=loader_helper, layer=Layer 1, frame=1:Line 1: Clip events are permitted only for movie clip instances

onClipEvent(enterFrame)
