Navigation inside a movie clip problems

Hope I can explain this clearly, I will attache the fla

I have my navigation set up inside a movie clip that i have placed on the main stage. The movie clip navigation has movieclip buttons (that lee showed us to set up) in it that when pressed reveal other sections kinda like an accordian effect (almost identical to invisiblemonster.com buttons) the animation is done in the timeline. The action script for all of the buttons is inside the main movie AS. The problem is that when i click on my buttons that reveal the sub menu the only one that works properly is “3D” the other ones the buttons get real goofy going back to the original movieclip look. All of the sub buttons actually dont work either the name is not inputed and the it is not clickable. I’ve checked and changed all my instance names just to make sure.

here is the fla so you can look and see exactly the setup and maybe whats going on

there is a lot of code at the top that isnt important at the moment so it can be ignored it’ll be used later to position things on the stage

Any help would be much appreciated and thank you in advance
