Did you find this code on the RSI web page?

(Oh, I'm just kidding...)

I can't tell from the code what exactly you are trying
to do. You can find an article on my web page, however,
about cascading menu choices (all in their own top-level
bases), that can communicate back to the first widget.
It looks to me like the principle is the same.
