cflayoutarea tab dilemma

Hi-
I have an interesting quagmire any thoughts are greatly appreciated.

I have a multi part form that I broke into tabs using cflayoutarea. Understanding that a cflayoutarea using a form will submit to only that tab's window space is fine, but I need to be able to get other tabs to change their content when a user makes a form submission in the first tab. I know that binding is the way to go (my understanding according to the LiveDocs is that only a url binding will work?) but the proper syntax is simply escaping me. Anyone know how to reference a hidden form field value in tab1 from within tab2 and tab3? Also, when I'm all done editing the forms, how do I break out of the Ajax area on screen and get back to the main screen real estate, not the active Ajax window? For example, if I'm in tab3, all done with my form edits in all tabs, and want a "Done" button to take me back to the home page, how do I program that button - that is within the Ajax window - to let me navigate back in the the main screen and take the user to the home page? I'm using Model-Glue, so this has been quite the adventure.

Thanks in advance,

Rich
