title: WSS 3.0 Workflow - How to set a field value to null
body: <p>WSS 3.0</p>
  
  <p>I have a List that contains a text field, a check-box, and a Date field. When the check-box is ticked I want to set the date field to the current date, and when a check-box is un-ticked I want to set the Date field to blank (or null, I don't care which just as long as it appears blank).</p>
  
  <p>I have created a Custom Workflow using Sharepoint Designer which correctly handles the first situation - and inserts the current date as required. But I am unable to create a Workflow action that will set a Date field to null or blank. By default the Date field is not displaying a value (which is what I want) so I know it must be possible to reset it to be the same.</p>
  
  <p>Anyone have any ideas?</p>
