Please help RE: Preloader tutorial!

Hi,
I’m a newbie with Flash MX, but I’ve been following the tutorials and learning all the basic stuff. The problem I’m having is, I’ve done the tutorial titled “Percentage Preloader w/Load Bar” and was able to get everything working properly while following along. However, that was when the preloader executes before the main content, but ONLY when the content is a single image on one frame.

My original content is a whole site that is composed of 5 layers and 42 frames. Where exactly would I have to insert the preloader to make it work? I’ve tried adding the 4 layers from the tutorial to my timeline, and even moved my content over so that it starts on frame 3, but I still can’t get it to show the preloader progress. Is there anything about creating another scene in order to make it work, or is that unecessary?

Any help in this matter would be greatly appreciated!!! Thanks!
