I'm trying to add conditional formatting to highlight rows that have duplicate values. I followed direction from other questions/forums:
Format>Conditional formatting>
- Single Color
- Apply to range = A1:A988
- Format rules = Custom formula is COUNTIF(A:A,A1)>1
- Formating style = Fill color light green
However, none of the rows with duplicate values are being highlighted.
