title: Google Apps Script: How do I change my displayed selection with for class listBox code?
body: <p>I'm using Google Apps Script</p>
  
  <p>I have an on click event that changes some form Class TextBox values to null using the following  </p>
  
  <p>app.getElementById("name").setText("")</p>
  
  <p>How do I change my displayed selection for class listBox code?</p>
  
  <p>looking at class listbox </p>
  
  <p>I thought it might be something like </p>
  
  <p>app.getElementById("relationship").setItemText("** Please Select <strong>","</strong> Please Select **")</p>
  
  <p>but that doesn't work</p>
  
  <p>Any ideas?</p>
  
  <p>Regards,</p>
