I'm trying to conditionally format a group of cells where you take the top n from each region per period, ex. Top 5 from North, Top 3 from East, etc. The formula I used is =OR(AND($A2="North",B2>=LARGE(B$2:B$66,5)),AND($A2="South",B2>=LARGE(B$2:B$66,3)),AND($A2="East",B2>=LARGE(B$2:B$66,4)),AND($A2="West",B2>=LARGE(B$2:B$66,4))) but it seems to only pick up the top n of each period regardless of region. What am I doing wrong?
