August 2, 200718 yr Newbies Here is the basics of my dilema. edition code(calculation, from another table) + print number(user entered) = image number code(calculation) I need to validate that the PRINT NUMBER for the edition is unique so we do not duplicate print numbers. I have tried validation by calculation of the PRINT NUMBER, (since one can not validate a calculation), to no avail. Am I chasing my own tail? Do I need to provide more info to you, for help?
