    Dim iRow() As Integer
    Dim iRows() As Integer
    Dim i As Integer
    Dim j As Integer
    
    iRow = Sheets("Kontroll").Range("A2").CurrentRegion.Rows.Count
    iRows = Sheets("Kontroll").Range("B2").CurrentRegion.Rows.Count
    
    For i = LBound(iRow) To UBound(iRow)
        For j = LBound(iRows) To UBound(iRows)
            Name1 = Sheets("Controll").Range("A" & i).Value
            Name2 = Sheets("Controll").Range("B" & j).Value
            
            If Name1 <> Name2 Or Name2 <> Name1 Then
                Sheets("Controll").Range.Range("A" & j).Interior.Color = 255
