Hi!

I have a MC with an instance name of party and I have a tween animation very simple of a square going from alpha 0 to alpha 100. I have a stop() command at the beginning of the animation to start it stopped.  
I have this code at an actions frame :

```auto

btButton1.addEventListener(MouseEvent.CLICK,onButton1CLICK);

function onButton1CLICK(e:MouseEvent):void
{ 
  party.gotoAndPlay(1);    
}

```

I want to start the animation but it is not starting.  
I tried to put a trace statement inside this click method and it is not executing it neither.

what am I doing wrong?
