jrambo63,

Try this code:

Private Sub Worksheet_Change(ByVal Target As Excel.Range)
Dim oldValue As Double
Dim newValue As Double

If Target.Cells.Count 1 Then Exit Sub
If Intersect(Target, Range("C8:O9")) Is Nothing Then Exit Sub

If Not IsEmpty(Target.Value) And IsNumeric(Target.Value) Then
Application.EnableEvents = False
newValue = Target.Value
Application.Undo
oldValue = Target.Value
Target.Value = oldValue + newValue
Application.EnableEvents = True
End If

End Sub

I've learned to add an accumulator to multiple cells using the
code on http://www.mcgimpsey.com/excel/accumulator.html


Private Sub Worksheet_Change(ByVal Target As Excel.Range)
Static dAccumulator As Double
With Target
If Not Intersect(.Cells, Range("C8:O9")) Is Nothing Then
If Not IsEmpty(.Value) And IsNumeric(.Value) Then
dAccumulator = dAccumulator + .Value
Else
dAccumulator = 0
End If
Application.EnableEvents = False
.Value = dAccumulator
Application.EnableEvents = True
End If
End With
End Sub


I was able to get it working for the cells I needed, but I would like
accumulators running on multiple cells (all running a separate
accumulator). What do I need to change in the code to accomplish this?


The cells I need this for are C8 through O8 & C9 through O9

As it is set up now if I enter the value "5" into cell C8 and then add
another "5" into cell C8 then the new value is "10", which is great.
But when I also try to enter the value "5" into cell C9, the new value
becomes "15" instead of "5".

Thanks!
