Is cboComplete a check box or a combo box? I'm asking because usually a control name starting with 'cbo' is a combo box, but using a check box makes more sense.
If it is a check box you can add a combo box bound to the same field (just for testing). When you click the check box, the value in the combo box should toggle between 0 (false) and -1 (true).
I'm not sure what's going on. Make sure that the recordset type for the form is not set to 'Snapshot', and that there are no edit locks on the form or controls.
Anyone else have any suggestions??
