Marketo Modules not drag and droppable or editable

Hi all,

We are creating a Marketo template to have modules in and the container has been set at the <td> of the main table with the modules being table elements themselves.

The modules show up in the module pane but you can't drag them into the email and the one on the page by default is not editable.

I've made it as simple as possible to debug but does not work. Here is my code.

<table border="0" cellpadding="0" cellspacing="0" width="100%" style="min-width: 100%;">

  <tr>

    <td class="mktoContainer" id="MktContainer" style="max-width:100%;">

      <table class="mktoModule" id="test" mktoName="test">

        <tr>

        <td>

          <div class="mktoText" id="testText1" mktoName ="TestText1">

          Some Text

        </div>

         </td>

        </tr>

      </table>

      </td>

    <!-- END of Marketo Module Container -->

    </tr>

  </table>

Thanks!
