From: amiliab on
I have a form based on a main table of geographic features. However, for all
new records, I would like to have the Geography Feature ID field autofill
based on a separate table of allowable values. I would use the autonumber
format for this, however, the allowable values are a list of letter codes
(i.e. AAAA through to AAAZ). I already have several records with acceptable
codes...however I would like all future records to pull ID's from this table.

What would be the best way to go about this?
Any help would be greatly appreciated.

Thanks.
