Dim DuplicateFound As Boolean
For r = 1 To Range("A65536").End(xlUp).Row
CurrentValo = Range("O" & r).Value
CurrentValq = Range("Q" & r).Value
CurrentValu = Range("U" & r).Value
DuplicateFound = False
For r2 = r + 1 To Range("A65536").End(xlUp).Row
If Range("O" & r2).Value = CurrentValo And Range("Q" & r2).Value = CurrentValq And Range("U" & r2).Value = CurrentValu Then
DuplicateFound = True
If Range("N" & r2).Value <> "XX" Then
Range("A" & r2).EntireRow.Delete
r2 = r2 - 1
If DuplicateFound = True And Range("N" & r).Value <> "XX" Then
Range("A" & r).EntireRow.Delete
r = r - 1
