One way:

Private Sub Worksheet_Change(ByVal Target As Range)
With Target
If .Cells.Count 1 Then Exit Sub
On Error GoTo ErrHandler
Application.EnableEvents = False
If Not Intersect(.Cells, Range("C:E,L:N")) Is Nothing Then _
.Offset(0, 4).Value = .Offset(0, 4).Value + .Value
Cells(.Row, "U").Value = Cells(.Row, "G").Value + _
Cells(.Row, "P").Value
End With
ErrHandler:
Application.EnableEvents = True
On Error GoTo 0
End Sub

Hello, I have entered the code below and it works just great but my
problem is that at the end I add up the two accumulator cells but it
only works for one row how do I get it to work for all the rows? Thanks
in advance for any help given.
