do something like
unless (param('foo'))
{
'print out some HTML here describing the error'
exit;
}
This will check for the parameter you want to make sure is populated and
spit out an error at the user if not..
Also, you might want to have a look at 'perl for web site management' that
was just published since it's the best beginner cgi book I've seen.
