I am currently using this formula to identify duplicates,
=IF(COUNTIF([Invoice Number]885:[Invoice Number]1735, [Invoice Number]885) > 1, 1)
New lines are now doing this,
=IF(COUNTIF([Invoice Number]1002:#REF, [Invoice Number]1002) > 1, 1)
because the formula is looking for lines greater than the sheet currently, therefore, it says unparseable.
Any suggestions? Looking for an option that scans and identifies any duplicates for every row from 1 to whatever the last row number is, in every column. Instead of the last number changing every time
