Hi Barbara!
I was talking about a UNIQUE value for that field.
I did not think about a "counter", or auto-increment, or about a field set by AlmComplete in any way.
My proposal tries to describe just a field that cannot have the same value (either numeric or alphanumeric) in two or more "records"/"rows", and that in case the user "submits" a new record with a "unique" field with a non-allowed value (duplicated one) then AlmComplete should stop the submit action with a msg (maybe like "duplicate value on field xxxx is not allowed").
Regards (and thanks for support and quick replies)
