Yousoft,
One approach to consider here, go to Tools|Relationships, and define
Relationships between the main table and the tables that the subforms
are based on, with Referential Integrity, and Cascade Deletes. That
way, if you delete a main table record, all related records in the
linked tables will be automatically deleted.
