Hi all,
I am trying to write a perl script that will go to a web page (http://www.arabidopsis.org/Blast/),
select the right options from the drop down menus, fill in the Input text field, and then submit the form.
Here is my code:

#!/usr/local/bin/perl
use strict;
use lib "/common";
use LWP;


my $browser = LWP::UserAgent->new;
  
my $sequence = 'GTGACGAGGAGGAAGAAAGAGTGCGGTTGTTTTGTTTGACACTTCTTTTCTTTC

my $URL = "http://www.arabidopsis.org/Blast/";
#BLASTX:NT query, AA db  ->blastx 
#AGI Proteins (Protein)     ->ATH1_pep
#query sequence             ->QueryText
my $response = $browser->post( $URL,
    [ 'Algorithem' => 'blastx', 'BlastTargetSet' => 'ATH1_pep',
      'QueryText' => $sequence, 
    ]
);

my $page = "/common/perlscripts/WebReading/page.html";
open(OUT,">$page") or die "can't open ", $page;
print OUT $response->decoded_content;  
close(OUT);
[download]

I am trying to get the form to submit (the 'Run Blast' button), so that $response contains the data from the results page, but I can't figure out how to do that. If anyone knows a good web site for me to look or knows the answer, I would really appreciate it.
Thanks
Jon
