I am hoping a monk here can help me figure out what is going around with this fairly short login script. I'm trying to log in to http://www.justanswer.com/login.asp . There is a email and password field AND a radio button which must be set to 'returning' since I already have an account. The below script keeps coming back as if I never set the radio button saying I'm a user. The mech->content test print out shows my email filled out but the radio button isn't pushed. Can you see what I may be doing wrong? The relevant HTML code from what I can see is..

    <form name="aspnetForm" method="post" action="/account/sign-in.asp
+x" id="aspnetForm">
 <input class="JA_field" type="text" id="JA_email" name="email" maxlen
+gth="75" value="" tabindex="1" />
<input class="JA_field" type="password" id="JA_password" name="passwor
+d" maxlength="75" tabindex="5" />
 <input class="JA_radio" type="radio" id="JA_returning" name="sign_in_
+type" value="returning" tabindex="3" checked="checked"/>

My code is below.

use WWW::Mechanize;

my $email = '';
my $password = '';
my $ja_login = 'http://www.justanswer.com/login.asp';
my $answer_page = 'http://www.justanswer.com/expert/question-list.aspx
+';
my $confirm_signon = 'My Questions';


print header, start_html("JA");
my $mech = WWW::Mechanize->new(agent => 'InternetExplorer 8');
my $login_get = $mech->get($ja_login);

$mech->submit_form(
  form_name => 'aspnetForm',
  fields => {
    email => $email,
    password => $password, 
    sign_in_type => 'returning',},
);

if ($mech->content !~ m/$confirm_signon/)
{
   print "Failed to sign on";
print $mech->content;
   exit;
}

$mech->get($answer_page);
print $mech->content;
