I've created the following macro that removes data based on ofther
cell information. This is similar to duplicate row code, but I'm
looking to define which columns I evaluate. Currently, this macro
looks at just column A or 1. I need it to look at column A, C, F &
G. My question is more syntax based I believe as I'm at a beginner
level in creating VB/Macro code; otherwise this is working as needed -
can anyone assist on the range on this one?

'Removing Dupicates
Dim rng As Range
Dim i As Integer
Set rng = Range(Cells(1, 1), Cells(1, 1).End(xlDown))
For i = rng.Rows(rng.Rows.Count).Row To rng.Row + 1 Step -1
If Cells(i, 1).Value = Cells(i - 1, 1) Then
Cells(i, 6).ClearContents
Cells(i, 7).ClearContents
Cells(i, 8).ClearContents
Cells(i, 9).ClearContents
End If
