Hi Michael

If you don't mind having the data sorted then this is one way to get rid
of duplicates (assumes we are still talking about the range ("A2:D100"):

Sub dups()
Dim i As Integer
Range("A2:D100").Sort Key1:=Range("B2"), Order1:=xlAscending _
, Key2:=Range("C2"), Order2:=xlAscending, Header:=xlNo
For i = 100 To 2 Step -1
If Cells(i, 2).Value = Cells(i - 1, 2).Value And _
Cells(i, 3).Value = Cells(i - 1, 3).Value Then
Rows(i).Delete
End If
Next i
End Sub

Rowan,

Thanks for the code. I'll work on figuring out how it works (I don't
like to 'copy and paste'. I like to learn something along the way).

Here's an example:

datacol1 datacol2 datacol3 datacol4
row1 A B C C
row2 A C B D
row3 Z B C A
row4 Y C B H

In this example, I want to match on datacol2 and datacol3. Based on
that,
row1 = row3 and row2 = row4. I dissregard datacol1 and datacol4. I
want to keep row1 and row2 in this scenerio.

Thanks.
