Slight modification needed - probably take most 3 minutes to figure out

The code works except it compares column A values with column B values and prints out the values in column A and not column B

[VBA]Sub compareColumns()
Const TEST_COLUMN As String = "A" '<=== change to suit
Dim i As Long
Dim LastRow As Long
Dim NextRow As Long

With ActiveSheet

LastRow = .Cells(.Rows.Count, TEST_COLUMN).End(xlUp).Row
For i = 1 To LastRow

If IsError(Application.Match(.Cells(i, TEST_COLUMN).Value, .Columns(2), 0)) Then

NextRow = NextRow + 1
.Cells(i, TEST_COLUMN).Copy .Cells(NextRow, "C")
End If
Next i

End With

End Sub
[/VBA]

How do I change this such that the code prints values in both column A and B in column C? So, column C has the values that are in both A and B.

thx

Sub compareColumns()
Const TEST_COLUMN As String = "A" '<=== change to suit
Dim i As Long
Dim LastRow As Long
Dim NextRow As Long

With ActiveSheet

LastRow = .Cells(.Rows.Count, TEST_COLUMN).End(xlUp).Row
For i = 1 To LastRow

If IsError(Application.Match(.Cells(i, TEST_COLUMN).Value, .Columns(2), 0)) Then

NextRow = NextRow + 1
.Cells(NextRow, "C") = .Cells(i, TEST_COLUMN).Value & _
.Cells(i, TEST_COLUMN).Offset(0, 1).Value
End If
Next i

End With

End Sub

Thanks so much. Need some more help though.

The result is that it adds the value of column A and column B together in column C.

For example column A has value "hello" and B has "bye", then "hellobye" is printed in C.

If cell A2 has value "hello" and B38 also has "hello", then "hello" should be printed in column C.

Much appreciated!!

Then just add that test?

[vba]

Sub compareColumns()
Const TEST_COLUMN As String = "A" '<=== change to suit
Dim i As Long
Dim LastRow As Long
Dim NextRow As Long

With ActiveSheet

LastRow = .Cells(.Rows.Count, TEST_COLUMN).End(xlUp).Row
For i = 1 To LastRow

If IsError(Application.Match(.Cells(i, TEST_COLUMN).Value, .Columns(2), 0)) Then

NextRow = NextRow + 1
If .Cells(i TEST_COLUMN).Value = .Cells(i, TEST_COLUMN).Offset(0,1).Value then
.Cells(NextRow, "C") = .Cells(i, TEST_COLUMN).Value
Else
.Cells(NextRow, "C") = .Cells(i, TEST_COLUMN).Value & _
.Cells(i, TEST_COLUMN).Offset(0, 1).Value
End If
End If
Next i

End With

End Sub

Thanks, I'm lost!!

Does lost mean sorted or not?
