I need the following script to run as soon the as the play head comes on the frame. Right now it is activated through an onRelease…need to replace that:

myButton\_btn.onRelease = function() {  
tweenBall(mx.transitions.easing.Strong.easeOut);  
};  
function tweenBall(easeType) {  
var begin = -50;  
var end = 100;  
var time = 20;  
var mc = ball\_mc;  
ballTween = new mx.transitions.Tween(mc, “\_y”, easeType, begin, end, time);  
}
