How to disableall a menu button function

Hey Everyone.

How would i disableall a menu button after i’m in that part of the menu, so i cant’nt keep clicking on it and getting my transition effect?

This is the function for my menu button.

futbol_mc.onRelease=function(){
myName=this._name;
subNav(myName);
trans2.gotoAndPlay(“tran”);
}

Any help would be awesome, many thanks :te:
