Auto Sum entries in a cell
 

Hi, let's say I entered 5 in A1 and then the next day I updated the cell to
6. Can Excel total these two entries in A1 to get a total of 11. I don't
want to use a separate cell to add up each entry.

Your help is greatly appreciated

Auto Sum entries in a cell
 

Mike,

Add this to a standard module

Option Explicit
Public myValue As Double


Add these two to the worksheet's codemodule

Private Sub Worksheet_Change(ByVal Target As Range)
If Target.Address = "$A$1" Then
Application.EnableEvents = False
Target.Value = Target.Value + myValue
myValue = Target.Value
Application.EnableEvents = True
End If
End Sub

Private Sub Worksheet_SelectionChange(ByVal Target As Range)
If Target.Address = "$A$1" Then myValue = Target.Value
End Sub


Add this to the workbook's code module, changing the Sheet1 to the correct sheet name:

Private Sub Workbook_Open()
myValue = Worksheets("Sheet1").Range("A1").Value
End Sub

HTH,

Bernie's code will do the job, but you will have no "audit trail" in the
event of incorrect data input.

This can lead to problems.
