Thank you Svein, that's what I tried but kept getting: SQL error code = -104. Invalid expression in the select list (not contained in either an aggregate function or the GROUP BY clause).
and yet it now works. I thought it must have been because I was accessing code in the iif(...). I must have had a typo that I could not see for looking. Anyway, that now works perfectly, without the ',' after SH.
