I agree. Sorry about that.

This sub is what is currently working to log me in to Yahoo with ActivePerl:

sub login{

    print "Logging in to Yahoo...";

     #set url to page requiring login and password
    my $url = 'http://login.yahoo.com/config/login?.done=http://fantas
+ysports.yahoo.com&.src=spt&.intl=us';
    $mech->get( $url ) or die("Could not get $url\n");

     #these two fields were specfic to the Yahoo login HTML field name
+s 
     #for login and password.     
     
    $mech->field("login", 'my_username');
    $mech->field("passwd", 'my_password');
    $mech->click();

    print "Done.\n";

}#sub login
[download]

And the original error message was actually with the $mech->field() methods. They failed on the Linux box first. After re-reading the documentation on CPAN, I tried a different way of setting the values for those fields, and I was able to fix that problem by using this code instead of the two $mech->field lines above above:

$mech->set_visible( "my_username", "my_password");
[download]

However, apparently the submission is not working because I am not downloading the HTML content that should be there after logging in. It actually downloads an HTML page telling me that I haven't logged in.

So now my linux box code looked like this:

sub login{

    print "Logging in to Yahoo...";

     #set url to page requiring login and password
    my $url = 'http://login.yahoo.com/config/login?.done=http://fantas
+ysports.yahoo.com&.src=spt&.intl=us';
    $mech->get( $url ) or die("Could not get $url\n");

     #these two fields were specfic to the Yahoo login HTML field name
+s 
     #for login and password.     
     
    $mech->set_visible( "my_username", "my_password");
    $mech->click();

    print "Done.\n";

}#sub login
[download]

That's when I began Dumping the form to make sure the login and password fields were actually being set to the correct values, and they are.

So tried a few other submission methods other than $mech->click(). Like the following:

$mech->submit();
[download]

...and...

my $button = $mech->current_form()->find_input(undef, "submit");
$mech->click_button(input => $button)
[download]

None of these worked. Again, any help would be greatly appreciated.
