Dropdown menu not working

I've attached the .fla.

I have created a simple rollover dropdown menu. The rollover makes visible its submenu via actionscript (visible=1). When I use on (release) handler, the menu item doesn't go to its assigned frame label.

Can someone help?

Also can someone point me to some tutorial that covers all the angles of different dynamic menus. I've bought 15 books and to this day have not fopund a comprehensive source. And I've visited several forums and am tired of sifting through understanding code that seems too complex for sucha simple task. I guess what I'm saying is I'd like to create dynamic menus with simple scripting. Can it be that hard?
