Re: [MS_AccessPros] Help with subform

 

Rod-

Either you have a corrupted form, or you have some code that is interfering with the setting of the key on the subform.  Do you have any code in the subform?

I have a form and subform combination.  The main form has a table as source and the subform with a separate table.  The two forms use a master and child fields "ID_Question".  ID_Question is the primary key on the main form and a normal field on the subform.

When I open the main form with a filter, its filtered records appear.  If the subform has no data everything appears good.  When new data is added to the subform the associated ID_Question appears correctly but the primary key of the subform data is the count of records + 1 of the filtered main form.  Example:  when the filter return 7 records and new data is added to the subform the primary is set to 8 instead of the next record in the table thereby causing an error of duplicate primary key values.
