title: Google Form can't submit when launched in iFrame from Google Sheets
body: <p>I have created a Google Form and linked it to a Google sheet. </p>
  
  <p>I used a script from <a href="https://stackoverflow.com/questions/17152120/single-google-form-for-multiple-sheets/17156383#17156383">Single Google Form for multiple Sheets</a> and that loads the form OK.  </p>
  
  <p>However it can't be submitted and selections multiple choice questions don't work.  I set the permissions for the Google to "anyone can edit". </p>
  
  <p>How can I get the form to be successfully submit from in an iFrame?</p>
