Thank you everyone for your very useful comments and suggestions. Due to some of the modules that you suggested using not being installed (and me not knowing what to do about getting them installed - I've only worked here a week and a half and never used Perl before, but I digress) I decided that the easiest thing to do would probably be to code the form into the Perl and use self_url. It's working perfectly (well, that bit of the script :P ) and it certainly helped me get my head round some of the things I had been trying to avoid in Perl (read: OOP).

Thanks again :)
