[AccessD] Datasheet view validation

Hi All,

I have a form that has as its record source a query that joins two tables
together in a one-to-many relationship (outer join). I am displaying this
form as a datasheet.
The query is designed so that there will never be any records that match on
the "many" side when it is first opened. The query only displays two
columns. One from the "one" side and one from the "many" side.
As I have it now, a user could close the form without entering data into the
field from the "many" side, thus not creating a record on the "many" side.

How can I verify that the user has entered data in the field from the "many"
side for every record that is displayed? I don't want to restrict the row
order in which they enter data but I do want to make sure that the field for
each row is filled in before they close the form.

Thanks!
JR
