title: Insert/replace string in existing text form field in Word (VBA)
body: <p>So I'm trying to create a conditional dropdown in Word. I've used a Legacy Drop-Down Form Field with multiple options.</p>
  
  <p>What I want to happen is when one of the options is selected from the dropdown (and then I guess you have to Tab to enter it...), the Legacy Text Form Field below, that has a simple default text, should populate with a new string from the case statement.</p>
  
  <p>Things that I've already done/got working:</p>
  
  <ul>
  <li>the drop down is working, and on exit it runs a macro</li>
  <li>case statement is written out</li>
  <li>the result of the case statement is in a variable (string type), let's call it StringVar</li>
  <li>can pull the text form field's text (default text) with ActiveDocument.FormFields("TextBox").Result</li>
  </ul>
  
  <p>What I figure out, however, is how to replace the default text in the already existing Text Form Field with the case statement's string variable text.</p>
  
  <p>I've tried 
  ActiveDocument.FormFields("TextBox").Result = StringVar</p>
  
  <p>but it doesn't change anything inside the text form field. The default text is still there.</p>
