<<One of the values problelly contains a null value>>

No, it's a lookup table--there are no null values in it. As I said, somehow
a CRLF got where it looks like a plain ol' space character is.

Copying the value (from DBWB) into Notepad changed its appearance from:

Respiratory Therapist

To:

Respiratory
Therapist

IOW, it looked fine in DBWB, but in my combo box it looked like:

Respiratory || Therapist
