I'm having some /more than likely logical/ problems with building and returning forms using CGI::Application::ValidateRM. This is a fairly new module to access Data::FormValidator using CGI::Application's interface.

The module looks good, and it looks like it will hoenstly work, but I've just got problems passing paramters around through CGI. So don't worry about the choice of module, but concentrate on how I'm /not/ passing arguments between subs.

_form_register_profile should pick up $q->param{email} from the form, but doesn't for some reason. Well the reason being that I haven't passed it, I'm sure -- but I need help on how to do this. If anyone understands my cryptic question-answering strategy and can help me out it'd be most appreciated.
