[AccessD] OT: Excel Worksheet_Change event

Use the worksheet Calculate event handler:
Here is a simple 1 cell example...

Private Sub Worksheet_Calculate()

Const CELLTOCHECK as String = "E14" ' this can also be a global variable or
constant
Static vPrev as Variant
Dim vCurr as Variant

vCurr = Activesheet.Range(CELLTOCHECK).Value
If vCurr <> vPrev Then
  DoSomething
  vPrev = vCurr ' persist the current value
End If

End Sub

Private Sub DoSomething()
' logic goes here to perform some function when a cell changes
End Sub
