To add a new record either add a command button with the appropriate procedure on the on click event. Your query will be updated when you close the form. If you want to update the query when clicking the ADD button again you have to add the
Me.Requery to the event procedure.
If you want to delete a record you have to select the record by either using the navigation buttons or import a listbox or combo box on your form. Again you will have to set the
Me.Requery
to the on click event of the form as well as to the box if appropriate.
Let me know if this helps
