Praystation Menu system

By now you all know http://www.praystation.com

I am building a site that has a very similar menu system.

I cannot figure out how to get each of the different frames to communicate with each other like http://www.joshuadavis.com.

For example, if a user clicked on “print” button in left menu, how does that load all the relevant print.swf file (the corresponding sub-nav to the right). Further more, how does that load the first print selection in the main window - in what appears to be another SWF sitting in its own HTML frame?

In www.joshuadavis.com it looks like the left nav, the sub nav and the main content viewing area are all three separate SWFs sitting on 3 different HTML pages…each one apparently referencing the other.

I dont know man.

Thoughts?
