Professional :: Create A "replay" Button On The Last Frame Of Movie?

I want to create a "replay" button on the last frame of my movie but it's not working.
 
Here's what I did.
 
1. I created a layer named "Actions" and in my last frame (frame 900) I created a "Stop" action.

2. I then created a button and saved it to my Library.

3. I then created a new layer named "Replay Btn" and created a keyframe in the last frame of the movie (frame 900). I then dragged the button onto the stage so it was in the last keyframe (frame 900) and made it into a button Symbol.

4. In the Properties Inspector I then typed in an "instance" name of "replay".

5. Then in the layer named "Replay Btn" I selected the last frame of my movie (frame 900) and added a keyframe in the same layer as my button. I then opened the "Actions" panel and entered this code.

replay.onRelease = function() {
gotoAndPlay(1);
}

6. I then did a "Publish Preview" of the movie and got this error:
 
"Warning 1090: Migration Issue: The onRelease event handler is not triggered automatically by Flash Player at run time in Actionscript 3.0. You must first register this handler for the event using addEventListener ('click', callback_handler) In Actionscript 3.0, code cannot be placed directly on objects. select a frame or use the code snippets panel to apply code to the current selection on stage."
 
I understand that I must select the layer and "right-click" to add an action instead of selecting the object on the stage, but I guess I'm just not sure how to get the "Replay" button to work in CS5. I've watched a couple of tutorials but they weren't done very well and were really hard to understand. I just want to create a button to replay the movie.
