and if you make a mistake entering the number, what do you want to have
happen (if you forget what number you entered; but you know it is wrong,
then what). Generally a running total with no audit trail can be
problematic.

I am not a programer. How do it open the cell code and put this in there?
Thanks.

Try putting this into the worksheet code where you want this to occur,
the
input cell is A1 the summation cell is B1

Private Sub Worksheet_SelectionChange(ByVal Target As Range)
If Range("A1").Value 0 Then
Range("B1").Value = Range("B1").Value + Range("A1").Value
Range("A1").Value = ""
End If
End Sub

Cheers

I want to enter a number into a cell and this number will
automatically
add
its value into another cell. However, after the pressing the enter
key,
I
want the entered number to be disappeared, leaving room for the next
number.
How can I accomplish this? Or is this possible?
