Help with actionscript button

Having problems in changin kirupa’s tutorial, complex button (link). Trying to change it from an http button to a gotoAnd Stop (); button. Here’s the segment which deals with that:

this.onRelease = function(){

gotoAndStop (81);


The button’s rollover and rollout animation works fine but the button itself does nothing when clicked. Any help for a newbie to actionscript would be greatly appreciated.
