Passing FlashVars to swf from html

So I’m building a Flash/HTML hybrid website that uses a Flash navigation. Within the index.html file there is an Iframe that loads the different pages of content. I used this method so the whole page didn’t have to refresh only the content being loaded.

Well I have some buttons on the inner pages that will redirect to other inner pages. The problem with this is the Flash navigation is still stuck on the old page. The Flash nav says you’re on the home page while the content being displayed is the about page. Get it?

I’ve looked into some articles on using FlashVars but it doesn’t really apply to my site because of the Iframe.

Anybody have any idea how I would go about doing this or have you ever done this before?

Thanks!
