Hello.

Hope you can help. I have a button that has a controller in order to make it interactive as the user rolls over and out. The button is actually a movie clip, containing a video that simply has a build in and out effect which is triggered by the following:

this.music\_bk.onRollOver = function() {  
music\_bk.gotoAndPlay("\_over");  
}

this.music\_bk.onRollOut = function() {  
music\_bk.gotoAndPlay("\_out");  
}
