I would not normally recommend that unless there is only one user and never any intention of more than one user. Besides that creating a system parameter table to hold and supply constant values to the application is always a good idea anyway. Once this table is established you will find lots of uses for it. Now don't misunderstand, if you need to save this unique number for later use than by all means store it back into the draw point but I would not use that location to pull the next number.
Having fun with Access, always.
