Bruce,
>> I suspect though this would lead to a LOT of "almost duplicate" records with bad spellings etc.
I am fully aware of that but I am willing to take the risc. I don't expect that many records in that particular table.
Additional question:
At this moment, when I type a new value, (without your suggestion worked out), the entry field blanks out as soon as I tab to the next field.
Will this remain this way or will the new value be kept in the entry field, because the record now exists (after your suggestion is worked out?)
Cheers,
René
