Actionscript 3.0 :: MovieClips In Array Not Playing?

I'm trying to make a menu that has multiple movie clips as buttons and control them all with an array and one event listener. There will be many movieClip buttons on my page but for now I have two animated movieClips each with a stop(); action on fram one. The movieClips have 15 frames of animation. The main timeline of my movie has only 1 frame. Each movie clip is on it's own layer. If I create an event listener without the array I can get the buttons to work individually but when using the Array I can't get it to work.

Code:
Select allvar buttonArray : Array = [btnA, btnB,];
for each (var button : MovieClip in buttonArray) {
button.addEventListener(MouseEvent.CLICK, _handleMouseEvents);
} function _handleMouseEvents(event:MouseEvent):void {
gotoAndPlay(1);
}

When I use the trace function instead of gotoAndPlay(1); it works perfect?
Code: Select allvar buttonArray : Array = [btnA, btnB,];
for each (var button : MovieClip in buttonArray) {
button.addEventListener(MouseEvent.CLICK, _handleMouseEvents);
}
