keep from duplicating numbers when creating a list

J

JoelAM

I am creating a list of numbers and as the list grows I
sometimes enter in a number inwhich I had entered
previously unknowningly, is there a way to make a spread
sheet so that if I enter a number say 123456 and if later
enter that same number thinking it is a new number, it
will let me know that the number is already on the list?
