title: Refresh query-driven combo box values when field value changes?
body: <p>I have a combo box on an form where the values are populated based on the value in a separate field.</p>
  
  <p>To do this, I have created a combo box and set the "Row Source" to run a SQL statement.</p>
  
  <p>The problem I am having is that if the data in the field changes, the combo box values do not update.</p>
  
  <p>How do I get access to re-run the query?</p>
