Here's my dilemma...

I have 37 different worksheets (one for each major principal in my company)
that are to be updated on a semi-regular basis. I would like for each of
these worksheets to have its own time/date stamp that automatically updates
itself to the current date and time whenever a change is made on the
worksheet. The time/date stamp on one sheet must be independent of the
time/date stamps on all other sheets. In other words, when the time and date
is updated on one sheet none of the other time/date stamps on the other
sheets change unless they are modified as well. I have tried using
SendKeys...I thought I had something, but it seemed too complicated to get it
to work. And I've also tried using the Worksheet_Change event...I've been
tinkering with this code:

Private Sub Worksheet_Change(ByVal Target As Range)

'THIS SUB UPDATES THE DATE/TIME STAMP WHENEVER A CHANGE IS MADE TO A
PRINCIPAL'S SHEET
'Update "Date" cell
Dim Cell As Range
For Each Cell In Target
With Cell
If .Column = Range("B:B").Column Then
Cells(.Row, "F").Value = Int(now)
End If
End With
Next Cell

End Sub

Can someone please advise? Thanks!
