Question on tutorial "transition using external swfs

Hello! I have my main timeline which has a .swf loaded on it, and this swf moves (image scrolls left to right). I want that swf to stay put, and then load, when user clicks on a button, other pages (of course, one at a time) on top of this one.

How is this done? Basically loading swfs on top of other swfs, and then having the current one replaced, all the while having one at the root level.

I hope this makes sense…here’s what I’m working on:
