getting multiple buttons to play the same animation.

[Karacature]

I have a popup text box that I have run it's animation every time a certain button is clicked....and that works. However, when a different button is clicked, that has the same function on it, it won't animate.....and the first button will no longer run it either. I have a trace on the function that shows it is still working, but the animation itself no longer plays.

this part works, but only until a different button is pressed, then it no longer does.

this.popUpAnim_mc.gotoAndPlay("anim");

this.hot_btn.addEventListener(MouseEvent.CLICK, popAnim);

function popAnim(myevent:MouseEvent):void{
	this.popUpAnim_mc.gotoAndPlay("anim");
trace("popUp animated slide");
}

Here is one of the other buttons I want to also run the animation. It has another function as well, and I will include all of it's code, in case I'm overlooking something that's causing it to break.

Object(this).popUpAnim_mc.PopUp_mc.back_btn.addEventListener (MouseEvent.CLICK, backClick);
function backClick (myevent:MouseEvent):void {
	this.gotoAndStop(currentFrame-1);
}
//Hide Button on Frame 1
Object(this).popUpAnim_mc.PopUp_mc.back_btn.visible=false;
//constantly check current frame to determine if it should be hidden
this.addEventListener (Event.ENTER_FRAME, BackButtonVis);
function BackButtonVis (event:Event):void{
if(this.currentFrame==1||(currentFrame==totalFrames)){
	Object(this).popUpAnim_mc.PopUp_mc.back_btn.visible=false;
}else{
	Object(this).popUpAnim_mc.PopUp_mc.back_btn.visible=true;
}
}
this.popUpAnim_mc.PopUp_mc.back_btn.addEventListener(MouseEvent.CLICK, popAnim);

there are two other buttons that have different functions that I want to also run the animation...but if I can just get one to work, I'm hoping the other two will be easy.

Thanks in advance!
