assign quantity based on Item name?

Hi,

I took your solution of:

case floor({custentity6}/500) when 0 then 'C' when 1 then 'B' else 'A' end

and trying to apply it somewhere else:  (I'm trying to be creative) :rolleyes:

case floor {item} when "item1" OR "item2" then '1' when "item3" OR "item4" then '2' else '3' end

basically if the name of my item is "item1" (or 2)  assign 1

2. does this field have to be integer or could be free-form?
3. what is floor? part of the language or can I rename it?

thanks,
Yosi
