When you have multiple pages, and the content of each one depends on the one's before it, you need a way of maintaining 'state'. HTML is a stateless protocol, so this can be a little tricky. There are many ways to deal with this problem: passing data in the URL, passing data with hidden parameters, passing data with cookies, etc. But the BEST way (IMO) is to use something like CGI::Session, which plays nicely with CGI::Application, BTW. This lets you maintain state on the server side, and all you have to store client side (via cookie) is a unique session ID.
