Hey, all.
I have a perl script which generates the html listed below. I cleaned it
up a bit since the perl CGI module creates some really ugly html code.
I've looked at this thing 8 ways to Sunday, but I can't see anything wrong.
When I hit the "Add" button, it immediately executes the action of the form
skipping the validate_form function completely.
I've tried the script section towards the top of the html as well as
just before the </body></html> without success.
I'm betting it's a simple mistake, but for the life of me, I can't find
it. Can someone tell me what I've screwed up?
Thanks for your time.
Doug O'Leary
