Itís been a few years since Iíve done any sort of work with programming or databases. Even when I did, I wasnít very proficient, so please bear with me if Iím stumbling over something very basic...

Iím playing around with an Access Database and am trying to use VBA to change the criteria of a query. I have a form (frmProjects) that is based on a query (qryProjects). One of the fields is DateCompleted. The query is set to pull all records, but Iíd like the user to be able to click a command button and set criteria for the DateCompleted field to restrict the query to show only those records that have no date in that field, then refresh the form to show the updated query results. However Iíve forgotten more VBA than I ever knew apparently and none of the variations of code Iím using is working. Would anyone be willing to set me on the right path with this?
