Add some GUI functionality

Hi

I need to ask the user a "double" set of questions- He has to select from a list what items to run, and then for each item he has to select some subitems. In the moment I use "Prompt for variables Enhanced", and then I run a loop and for each selected item I show another form of  "Prompt for variables Enhanced". I would like to do the whole thing in one form - it could be in a tree form or each selection could open a sub menu. I am planning to write a small program in Delphi to do it, but it would be nice to have such an action in FB Because FB is so powerful and fun , I always prefer to use FB instead of combining other scripts...

Thanks Daphna Levin
