One way would be to have all the elements present but only show those elements that are set. Then every time the user submits the form all values are included. An alternative would be to use sessions (CGI::Sessions) and store the info in there until you want to process it. A third way (i'm sure there are more but this is what i've got so far) would be to somehow incode the values and store them in a single hidden feild on each page. Perhaps using Storable to store a hash with all the values. You do want to make sure that you are using post instead of get (or vice versa i can never remember - the one that doesn't make them part of the URL). The reason being that URL's can be subjected to unwanted size limitations by certain evil browsers.
