title: Facebook FBML issue - req-choice required as part of request-form content?
body: <p>When I try to send invitations from my site, I am getting this error, "req-choice required as part of request-form content". What does it mean?</p>
  
  <p>These are the details I gave when I created application:</p>
  
  <pre><code>App. Name : mysitename
  ConnectURL: http://www.mysite.com/
  </code></pre>
  
  <p>Below is the code I am using. Am I missing something?</p>
  
  <pre><code>&lt;fb:serverfbml style="background-color:#F7F7F7;"&gt;
      &lt;script type="text/fbml"&gt;
          &lt;fb:fbml&gt;
              &lt;fb:request-form
                    action='http://www.mysite.com/confirm.php'
                    method='POST'
                    invite='true'
                    type='mysite'
                    content='Come and join us. Visit us at http://www.mysite.com/'
                    &lt;fb:req-choice url='http://www.mysite.com/' label='Join'/&gt;
                    &lt;fb:multi-friend-selector
                    showborder='false'
                    actiontext='Invite your friends to join'
                    rows='4'
                  /&gt;
              &lt;/fb:request-form&gt;
          &lt;/fb:fbml&gt;
      &lt;/script&gt;
  &lt;/fb:serverfbml&gt;
