I have a form whose data source is a query that produces a subset of table 1. The subform's data source is table 2 and is linked to the form record by a common ID. When the form opens to its first record the subform is blank although there are corresponding records. If I scroll the form to the next record then go back to the first record, the subform displays the correct data. Except for this form-opening anomaly the form/subform works perfectly. I'd appreciate any ideas why this happens and what to do about it. Thanks.
