Quickform and Groups within groups

Hello, I am trying to build a program that reads a config file and uses that config to build my form. I want to be able to place groups within groups and still be able to set the default value and rules. I am wondering if it really works with groups within groups (so far I haven't been succesful in getting the data once the enclosing group is built) and how would it be possible to set their default values (especially since some of the elements inside the inner groups would have the same name such as radio boxes that have the same name). Thank you. Trevan tdr32@cs.byu.edu
