I have a combo box that I use to filter the records used in a form. Basically, the forms record source is a query with the combo box control value as a parameter. I requery in the after_update of the combo box. I have the same form in Access 97 and 2000. The 97 version works fine. In the 2000 version, the selected value will not show if the number of records returned by the filter is zero. As long as I get something back from the filter, the value will show. Any thoughts? Is this a 2000 bug? TIA.
