Any way to tell a movie when to play?

Ok, basically what I want to accomplish is this:

I have some navigation that when you click on any of the 3 buttons they initially all load the same movie and they test to see if the other has loaded it already or not …

What my problem is, is to load what that button is for once the initial “background” movie has loaded …

So say I have ‘about’, ‘contact’, and ‘staff’ … I need to test for each one if the initial “background” movie has been loaded and if it hasn’t then load it, and then if it has then don’t worry about it and just load that particular button’s movie on top of the “background” movie …

That make sense?

Thanks for any help!

sounds easy post/email a fla or something and i will do it for you…

or i can try and explain it…but youd have to explain your movie structure a bit better…
