Drop Down Menu Coding

[Ultrakd]

Ok Im just a little confused on what to do. In my menu I have 2 drop downs. each one is a separate Movie Clip and inside that Movie Clip they have other buttons that are separate Movie Clip. I have a class set to the buttons for a rollover action but it isn't working. How do I set actions to Movie Clips that are in other Movie Clip? Like how would I add links to them?

Here is a copy of my AS3 Class and a copy of the drop down.

package {
  import flash.events.MouseEvent;
  import flash.display.MovieClip;

  public class DropClass extends MovieClip {
    public function DropClass() {
       addEventListener(MouseEvent.MOUSE_OVER, over);
       addEventListener(MouseEvent.MOUSE_OUT, out);
    }

    private function over(event:MouseEvent):void {
        gotoAndPlay(2);
    }
   
    private function out(event:MouseEvent):void {
        gotoAndPlay(7);
    }
  }
}

Thanks Chris
