title: Disable Check Box Based on Other Values
body: <p>I have a relatively simple Continuous Form.  There is an invisible Check Box, let's call it Frank.</p>
  
  <p>There is second Check Box (Ralph) which may be True or False.  There's also a text box with a date (RalphDate).</p>
  
  <p>If Frank is True, I don't want the user to be able to change Ralph or RalphDate, regardless of what is already there.  </p>
  
  <p>Now, RalphDate is easy in that I just use a Conditional Format to check the value of Frank which either enables or disables RalphDate.  This option is not available for a Check Box.</p>
  
  <p>I'm now stuck, because using some Visual Basic sets the state of all the Ralph boxes the same based on the value of the first Frank value it comes across.  The question therefore, is how do I disable only the associated Ralph Check Box based on the Frank Check Box being True?</p>
