im making a form and im using the London Perl Mongers form processing script for processing...however im having trouble. basicaly what i want to do is have the user input some numbers in some fields and just sum those values and print them in another field (or in another page generated when the form is submitted...whichever is easiest)...can anyone help me? how can i go about doing this...i dont have much knowledge in cgi/perl...anyone have an easy way to get around this? thanks
