Thanks SO much - duh - I guess I should have gotten that :) Stupid C# coders - Perl isn't for kids. :) On the off chance someone is as novice as me, on top of what the person suggested above... this is what worked:

#where $agent = WWW::Mechanize->new();
my $form = $agent->form_name('someformname');
$form->action('http://www.something.com/someform');
$agent->submit();
#doing a $form->submit(); - gives you a funny "unblessed 
#error" which took me a while to grok
