Targeting the properties of the mouse event: ROLL_OVER, MOUSE:DOWN

Question

Hi - I am targeting the states of the button ie: ROLL_OVER is tweened a little bigger.
Then I want it to go back to its original size.
BUT it doesn't recognise the start and reverse methods.
Scene 1, Layer 'Layer 2', Frame 1, Line 60    1061: Call to a possibly undefined method start through a reference with static type gs:TweenLite.
button.addEventListener(MouseEvent.ROLL_OVER, rollOverHandler, false, 0, true);
button.addEventListener(MouseEvent.MOUSE_DOWN, mouseDownHandler, false, 0, true);
//button.addEventListener(Event.MOUSE_UP, mouseUpHandler);
button.addEventListener(MouseEvent.ROLL_OUT, rollOutHandler, false, 0, true);
var myTween:TweenLite = new TweenLite(button,1,{scaleX:1.05,scaleY:1.05,onComplete:myReverseFunction});
function rollOverHandler(e:MouseEvent):void
    //TweenLite.to(button, 1, {scaleX:1.05, scaleY:1.05, ease:Elastic.easeOut});
    myTween.start();
function myReverseFunction():void
    myTween.reverse();

I took a look at the ASdocs for Tweenlite.
- http://www.greensock.com/as/docs/tween/_tweenlite.html -
Maybe try this.
private var myTween:TweenLite;
private function rollOverHandler(e:MouseEvent):void{
     myTween = TweenLite.to(button, 1, {scaleX:1.05, scaleY:1.05, ease:Elastic.easeOut, onComplete:myCompleteFunction});
     //TweenLite.to() returns a TweenLite instance that is now referenced (at class scope) by myTween;
private function myCompleteFunction():void{
     myTween.reverse();
If this doesnt work I'll have to take another look later tonight when I'm at my home machine..
Looking back over your original code..it all looks correct (although I can't test). I mean nothing pops out.--
You created a TweenLite instance outside of function scope (the documentation on greensocks site says this is fine even though its a static class) and referenced it within the same class scope.
