DAPs are less tolerant of queries than forms. Some queries that are
updatable in forms are not updatable in DAPs.
However, two common errors that can cause what you see:
(1) You didn't include the primary key of the record to be updated in
the DAP as an element (even if it's hidden).
(2) You didn't specify which table in the query is the UniqueRecordset.
