Flash screens and setInterval

My debut post in the forum is a question about Flash screens. I am using flash screens (type=form) to create a movie that consists of a main screen with 3 movies screens and one navigation slide.

What happens is the main screen contains a behaviour that loads the navigation screen. The navigation screen contains 3 buttons that load an external swf into one of the 3 movie screens.

Everything works great using the buttons. I have transitions and screen visibility behaviours working nicely.

What I would like to add is an interval to the movie screens that will automatically advance to the next screen after say 10 seconds.

I have seen a lot our there on flash slideshows using setInterval to automatically advance through and array of images. Is there something similar I could do for screens.

Suggestions??? Cheers.
