title: Enabling field visibility from combo box selection in Access 2007
body: <p>I have a form in Microsoft Access 2007 called System, and a combo box called Utility within this form.  Below this is yet another combo box called Utility_FOO, and I have disabled its visibility by default.  One of the options in Utilities is a checkbox labeled 'FOO.'  I want Utility_FOO to become visible whenever FOO is selected.</p>
  
  <p>I have tried creating a subroutine in Visual Basic that checks whether or not FOO is selected every time I select an item from the list (using onUpdate), but I cannot figure out how to check that specific entry.  Is there a simple way to do this?</p>
  
  <p>Thanks!</p>
