[CS3] [AS2] Help loading CSS to HTML

Okay, my problem is NOT with loading the CSS into the Flash like every tutorial and help sheet I've found.

It's using Flash and ActionScript (or Java) to load a specific CSS sheet to the html page the swf is embedded on.

I'm trying to make several different sheets. Then, I need my little menu (built in Flash) to be able to switch the sheet currently loaded to the page. I don't care if I have to incorporate js, I just want it to work and I don't have much time.

There is no existing XML, JS or AS, besides the standard ...runActiveContent.js

I have buttons. I need to know what to tell them to do to switch sheets.

They will be loading different colored themes, "thin" or "wide" screen, and different sized fonts, depending on the sheet selected.

Just like this one in the upper right:

That is what my client wants.

Any help is appreciated. Thanks!
