[F8] Folder effect, actionscript and buttons

Well as you might have picked up from the title, I'm not exactly sure how to ask this question (I'm a total noob), so I'll do my best, and hopefully the attachment fills in the gaps.

I'm trying to create a basic interface. I want the content to be displayed in a mock manila folder type thing, with tabs along the top showing the user where they are in the navigation. If the tab isn't active it should be the blue colour, when it is active, I want it to be white/light grey (see attachment). I've created the tabs as buttons and done a little bit of action scripting but just cant seem to get it to work how it should.

If anyone here can make sense of what I'm asking, has time to take a look at the attachment and can offer me any suggestions on how to get it working, it would be greatly appreciated.

Thanks :mrt:

C the attachment.
