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.

Dear Dr. Fanning,
Thank you for your prompt response, I read you codes and I think my
problem is I didn't register the second tlb by xmanager. Now the
problem has solved.
Thanks a lot!
