Metts518 : there could be several different causes. You give no indication of what kind of data you're dealing with, whether one of more of the columns involves some rounding to nearest whole digit or two decimal places or whatever. Rounding, which most of us think of as "rounding up" could be the cause of your issue. I just recently (in another thread in this forum) learned of what's called "Bankers' Rounding," a method to minimize what you may be experiencing.
