AS question

Hopefully you guys/girls can help me out with this.

Im making menu in flash were there are 4 buttons.
It looks like this.


CONTACT | DESIGNS | ABOUT ME | PORTFOLIO


As you can see underneath the buttons is some space, here i want to make a submenu where movie clips can be loaden with buttons.

Oke I made two buttons (check link) , contact and designs when a visitor presses on them a movie clip load (both buttons have a other mc) but when a visitor also presses on the other button the old button stays acive and thats the proble, so.

How can I make a other MC fadeout when a visitor clicks on a other button?
