Update: I'm using WWW::Mechanize. Other than Java support, is there much difference in the two? Here is my code:

        
#set initital webpage
$url="http://www.fedex.com/ratefinder/home?cc=US&language=en&link=1&li
+d=//Ship//Pack+Rates+Corp";
 
#open initial webpage
my $mech = WWW::Mechanize->new();  
$mech->get($url);  


while($line=<ZIPPAIRS>){
    
    $indexForm2 = "standAloneActionForm";
    $mech->form_name($indexForm2) ;
    
    
    chomp $line;
    ($Ozip, $Dzip)= split("\t",$line);
print " $Dzip $Ozip\n";

    #enter the zip codes and package weight of 3 lbs
    $mech->set_fields(
    origZip => $Ozip,
    destZip => $Dzip,
    totalPackageWeight =>"3",
        );   

    $mech->click_button(number=>3);
            

    #print current URL's html code to file 2
    my $results_html = $mech->content;
    print OUTFILEB $results_html;

        die "All Done.\n";

nothing prints to the file. I had $mech->click_button( value=>'Get Transit Time'); in where you had suggested to try using the button number. When I try the button number, I get an error "Can't call method "click" on an undefined value..... Sorry, I'm not very good with the boards. I have only used them a few times and haven't been on in over 6 months.
