Right now I have =IF(COUNTIF([Part Number]:[Part Number], [Part Number]1) > 1, 1)
If the part number in row matches up with another row, it lights up a flag. I want to be able to add two checkpoints...
If a "part number" and "ware" in one row matches up to another "part number" and "ware" on a different row, light up the flag.
Any help would be appreciated
