Button problem, please help

Simple coding delima. In a perfect world

  1. you have a button that when clicked forwards you to a labeled frame and stops after the movie clip contained on that labeled frame concludes

I’ve tried hybrids of every bit of coding that I can get my hands on, but I’m missing something crucial in my understanding.

If you could, please, look at my example and tell me what’s wrong with this coding.

stop();
function gotolion(MouseEvent):Void {this.gotoAndPlay(“lion”);
};
lio_btn.addEventListener(MouseEvent.CLICK,gotolion );

Thank you so much!!!
