in reply to web form submission help
If possible, I would suggest using WWW::Mechanize, which offers extensive examples and many articles for reference. Nodes using WWW::Mechanize abound here on PM; Super Search will undoubtedly turn up much helpful information.
Also, helpful modules such as HTTP::Recorder and WWW::Mechanize::Shell exist to help you automate the creation of your WWW::Mechanize scripts.
Update: For example, using HTTP::Recorder as described here produces the following snippet:
$agent->get('http://genome.ucsc.edu/cgi-bin/hgGateway'); $agent->form_name('mainForm'); $agent->field('clade', 'vertebrate'); $agent->field('org', 'Human'); $agent->field('db', 'hg17'); $agent->field('pix', '620'); $agent->field('position', 'NM_000747'); $agent->click('Submit');
And the "results" page looks something like this:
