Allow only one new record per form pop up use

[BFish via AccessMonster.com]

Hello again!

Please tell me if what I want to do is possible.

The situation:
I have created a pop up form to check table records for possible duplicates
and suggest use of an existing record. This form is continuous, has on open
allow additions set to false and command buttons ADD NEW and CANCEL. This
form has a control displayed in the header to compare the typed entry to
existing data. Upon clicking Add New I have coded allow additions and the
typed data is dropped into the new record to save additional typing and for
the user to update two additional required fields. I would like the user to
only be able to add the one record.

I thought programming the Data Entry Property to true on the add new click,
but I get a dirty record and the possibility of still adding a new record in
the continuous form.

As I am writing this question I wonder if a coding after new record update
for a dirty record save then setting allow additions false again might be an
answer.

Any help to steer my efforts in the right direction I would greatly
appreciate.

Thanks,

Bill Fischer
