Add the following script to the src iframed page within a custom HTML block.

<script type="text/javascript" src="/js/public/jquery-latest.min.js"></script>
<script type="text/javascript">
     // set no conflict mode for jquery
   var $jQ = jQuery.noConflict();

       // all form submits will open in a new window




<script >

MktoForms2.whenReady(function (form) {

    var form = MktoForms2.getForm(FORM_ID_HERE);

    form.onSuccess(function (values, followUpUrl)

    { = followUpUrl; return false;




To figure out what the form id is, the easiest way is to look at the embed code. It is the 4 digit number on the second line.
