gdform.php

[smk2004]

I'm using a gdform.php formmail from Godaddy for my website.  I have it working fine but the only functions I can use is subject, e-mail, and redirect.  Unfortunately, I can't get it to take a required e-mail before submitting.  In other words, I don't want people to submit the form without placing their e-mail.  I've posted my code below.  Can anyone please tell me how to make the email a required function?  Thanks a bunch!

 

<form action="gdform.php" method="post">

  <INPUT type="hidden" name="FormType" value="GDFORM.PHP">

      <input type="hidden" name="subject" value="Contact CTO">

  <input type="hidden" name="required" value="email">

  <input type="hidden" name="redirect" value="thankyou.htm">

        <table class="main-box" width="80%" border="0" align="center" cellpadding="5" cellspacing="0" style="font-size:110%; padding:10px 0">
