You probably want to use is the self_url of CGI.pm; this returns a URL with all the state information that you need, so that you don't need to keep filling in hidden fields for old data. Just pass this as the ACTION method for your FORM, and that data is carried across. Note that you might have to play with adding and deleting values from the CGI instance variable so that they don't show up in this URL (for example, the page of 3 that you are on).

However, while this will work, as the amount of data entered increases, it is probably better to save the state of the data in files or databases on your end, using a unique session id that you then pass to further URLs, and upon completion of the last page, actually transferring all that data from files or databased into the final storage location that it will be stored in. This will be less prone to security faults as well, since only one state item (the session id) is passed.
