title: MS Access Input Mask for Postcode
body: <p>Is there a way to set an input mask in MS Access 2007 so that certain elements are optional? UK postcodes can be in a number of formats: <code>LL00 0LL</code> or <code>L00 0LL</code> or even <code>LL00 L00LL</code>. For this particular assignment, I need only worry about the first two formats.</p>
  
  <p>So, is there a way for me to set the input mask so that the first letter is optional?</p>
