HitTest & gotoAndPlay Problem

I’m trying to create the same menu effect as group94.com where when the mouse is moved over a certain area, the menu appears by sliding down.

If you take a look at my fla, you will see that the tween([COLOR=Blue]gotoAndPlay(“rise”) [/COLOR]) doesn’t work the way it should. Can anyone help please?

onClipEvent (enterFrame) {

	this.hitTest(_root._xmouse, _root._ymouse, true) ? _parent.gotoAndPlay("rise") : _parent.gotoAndPlay("drop");

}

Cheers
