Try this - right click on your tab, view code, and paste this in (which would
run when changes are made to columns A, C, or F.

Private Sub Worksheet_Change(ByVal Target As Range)
If Intersect(Range("A:A, C:C, F:F"), Target) Is Nothing Then Exit Sub

Application.EnableEvents = False
MsgBox "Do Something"
Application.EnableEvents = True

End Sub

How can I have a macro run that copies cells down when creating a new entry?
I would like to have several different columns, when items are modified, to
run some code. How can I do this? I have found samples of is specific CELLS
are modified via intersect, but I am not sure how to have it done via column
changes.

Thanks
