May 8, 201312 yr I need to know how to set up a field to calculate the next model number. Currently the method is to find the max and add 1[Max(veh_SELF_type::Model ID) + 1]. This has worked in the past. Letters have recently been introduced for a certain type of item so the current method will need to be tweaked. I currently have 4 records for this new type of item (Model Nums - A001, A002, A003, A004). When I add a new item, the current method gives me model num "5" instead of "A005". Also, once the numbers get to A999, the next one will need to be B001. I also have to skip I, O and Q letters. I appreciate any help.
