How do I create an automatic 'date last updated' reference?

I would like to create a function that automatically returns the current date
if certain other specific cells are edited, i.e. it is a reference to the
last time cells on that row were updated.

Please help??

Thanks both of you, but neither options seem to update the date when (and
only when) the data in another cell is changed. For example, I would like
cell A3 to display the last date that cell A1 or A2 was updated.

I had a similar problem and Tom solved it for me in an earlier thread
with the following....
Hi,

Latest brainteaser,

I have a Excel 2000 pro workbook, in one of the spreadsheets I have
column (E) that uses a dropdown list (Data/Validation/List). I want the
next column (F) to automatically show the date that the entry to column
E was last changed or if there has been no change show a generic start
date....

Is this possible?
Click to expand...
------------------------------------------------------------------------

right click on the sheet tab and select view code. In the resulting
module
paste in code like this:

Private Sub Worksheet_Change(ByVal Target As Range)
If Target.Column = 5 Then
Cells(Target.Row, 6).Value = Now
Cells(Target.Row, 6).NumberFormat = "mm/dd/yyyy hh:mm"
Target.Offset(0, 1).EntireColumn.AutoFit
End If
End Sub

You can run a onetime macro to fill any empty cells

Sub FillWithGeneric()
Set rng = Columns(5).SpecialCells(xlConstants)
For Each cell In rng
With cell.Offset(0, 1)
If IsEmpty(.Value) Then
..Value = DateValue("01/01/2006") + TimeValue("08:00")
..NumberFormat = "mm/dd/yyyy hh:mm"
End If
End With
Next
Columns(5).AutoFit
End Sub

Hope this helps.
