Sorting out all the various states you can get with multiple forms can get messy really quickly if you try and handle it by yourself. You are better off using a module like CGI::Application which gives you a nice architecture for this type of thing.

Basically, your script becomes a small stub which just contains configuration information and the bulk of the code is in one or more modules which are made of subroutines which represent 'run-modes' or pages in yourapplication. You can navigate from page to page by calling different run-modes and store state in between. As a bonus it also has hooks into HTML::Template to keep your business logic seperate from your HTML. And you can use any of the functions from CGI.pm.
