Here is a very simple example that you can adapt.

Say we have a data entry area from G2 thru G65. If the user enters data in
this area, we want the date to be recorded in G66. Put the following event
macro in the worksheet code area:

Private Sub Worksheet_Change(ByVal Target As Range)
Dim r1 As Range, r2 As Range
Set t = Target
Set r1 = Range("G2:G65")
Set r2 = Range("G66")
If Intersect(t, r1) Is Nothing Then Exit Sub
Application.EnableEvents = False
r2.Value = Date
Application.EnableEvents = True
End Sub


Because it is worksheet code, it is very easy to install and use:

1. right-click the tab name near the bottom of the window
2. select View Code - this brings up a VBE window
3. paste the stuff in and close the VBE window

If you save the workbook, the macro will be saved with it.

To remove the macro:

1. bring up the VBE windows as above
2. clear the code out
3. close the VBE window

Hi there, hope somebody can help me!
I am puzzling with a problem: I have a excel 2003 wb with sheets where the
cells of 3 colums are representing the results of 1 day. In fact colums F:H
do have the results of day 1 of month January to December. Colums CC:CE the
results of day 31 of the month January to December. The cells where one can
put in or change the numeric data is the range: F2:CE65. Under each day, (3
merged colums of that day), I like to have the last update when someone has
changed the data in one of the 3 'day'colums. The problem I encounter is that
each time I reopen the workbook the 'Last update' has changed while there was
no change in the 3 colums. Also the 'Last update' in other sheets in my
workbook have changed but I want only the last updates per 'day' and sheet.
Tnx in advance!
