I've created a movie clip for a drop down menu for my navigation.

It's basically an opening and closing shape tween onRelease. But my menus aren't opening and closing. That's all I'm trying to fix right now.

The book I'm using Foundation Flash 8, has me putting the following script on my main timeline on a layer "Actions", Frame 1. This script points back to frame labels I've created for opening and closing on my subMenu movie clip.
Here's for one button:
btnHornet.onRelease = function() {
ToOpen = "open hornet";
if (userHasClicked == true) {
subMenu.play();
} else {
subMenu.gotoAndPlay(toOpen);
userHasClicked = true;
}
};

I have this on my close frame on my subMenu movie clip:
gotoAndPlay(_parent.toOpen);

I can't figure it out, and better solutions?
