Level II and III will be null so I would use the description of Level I but if those combo box are NOT NULL, i will be using Description of Level II or III. I would be happy if you could guide me through it ^_^. ![]() Sql Server Iif Isnull Statement· iif is null expression help Queries. & IIf([services1] Is Not NULL.
