Help with Flash movie

Hi i need some help on a movie im trying to build. I have attached the fla so u guys can see. What I want to happen is the text be individual movies(which they are) and have them link to an external movie that will be loaded in the center of the screen. I know the loadMoive command, but what I am stuck on is when I mouse over the movie buttons the other movie retracts( you’ll see that in the FLA.)
