>OK Mike, how do I do this with constants? Sundays are paid at a different rate here, so the DOW() is important. e.g. a user enters "30/04/00" (30 April 2000) and I respond, "Domingo". How do I do that with constants?

Ok, I didn't fully understand what you were trying to do with these values before, in this case, a method call, or a cross reference to an array will work. Sorry.
