[Ashakuras]

I'm desperate I am studying flash and use the cs5, I have a task, is to add play and stop buttons, has already done this but now my question is this.

What actions need to keep the animation should not start until you press the play button?

myButton.addEventListener(MouseEvent.CLICK, myFunction);
function myFunction(event:MouseEvent)
{

}

Instructions would in your case be:

yourAnimation.start();

or, if your animation started on frame 10, say:

gotoAndPlay(10);
