    Thank You message not appearing in after Form submission in iFrame

      I've crated a landing page with a Form inside of it.

      I am showing the landing page+form via an iFrame in a popup .

      The form shows up correctly and submits properly, but the Thank You message is never shown (still has the visibility=true inline style).


      I have 3 layers on my landing page.

      1. Header Graphic

      2. Form

      3. Thank You Message code:

      <script src="//app-ab13.marketo.com/js/forms2/js/forms2.min.js" type="text/javascript"></script>


      MktoForms2.whenReady(function (form){

      //Add an onSuccess handler

        form.onSuccess(function(values, followUpUrl){

         //get the form's jQuery element and hide it


         document.getElementById('confirmform').style.visibility = 'visible';

         //return false to prevent the submission handler from taking the lead to the follow up url.

         return false;




      <div id="confirmform" style="visibility:hidden;"><p><strong>Thank you. Check your email for details on your request.</strong></p></div>


      Any clue as to why the Thank You message never appears?
