ACC2000: "#Name?" or Control Is Blank on Form Based on a Query

If you have a form that is based on a query, and the query contains multiple fields with the same name (such as FieldA from Table1, and FieldA from Table2), the control(s) on the form that are bound to that field name will be blank or may display the "#Name?" error.

Because the same field name appears multiple times in the query that the form is based on, Access does not know which field to link to the control(s). Therefore, instead of making an assumption about which field to link to, it leaves the control(s) that are linked to duplicate field names blank or displays the "#Name?" error in the control.

To correct this behavior, rename the field in the query.

To change a field name in a query, follow these steps:

1. In a query's Design view, place the insertion point in front of the first letter of the field name in the query design grid.
2. Type the new name followed by a colon. Delete any names assigned by Access, but do not delete the field name or expression.

NOTE: If you change a field name in a query's Design view, it changes the heading in the query's Datasheet view and the field name in a form or a report based on the query. However, the underlying field name in the table does not change.
