I've got a solution for this with Data::FormValidator. I'm just looking for someone to help code it. :) It should be pretty straightforward-- I'm in a time crunch myself.

I would file a bug report against HTML::FillInForm for the issue you having it . If the module can get as far as it does-- correctly handling the populated fields, I think it ought to be able to handle the rest of them. Are you using the latest version, 1.01?
