Worksheet Change Event-when a cell with a certain range of cells) are changed?

Hello. How can I have a worksheet_Change event trigger only when certain
cells (more specifically - when a cell with a certain range of cells) are
changed? Thanks!

I don't think it is possible: the range object doesn't have any event that
can be triggered.
You have to understand what range generated the event inside the
worksheet_change event.

Private Sub Worksheet_Change(ByVal Target As Range)
If Not Intersect(Target, Range("C1:C5")) Is Nothing Then
MsgBox "Changed!"
End If
End Sub

Take care because Target may not always be just the single cell.

What are the cells?

Private Sub Worksheet_Change(ByVal Target As Range)
If Target.Address = "$A$1" Then
MsgBox ("ACTIVE")
Else
End If
End Sub

Ooh..his is better.

Thanks so much Rob! Can I ask a follow up to your post on the other message
I posted regarding the "before event"?

You posted "You must store the value separately as the cell changes so you
can refer to
the value at next change." How would I go about doing that? My goal in
this is to create a change log on a worksheet that multiple people will be
changing. Thanks again for your help!!

You're welcome.

You should really stick to the original thread.

I've never done change tracking this way before. I'm concerned I couldn't
capture every change - I could be wrong..

If I were to give it a serious go, I might create a two column table. First
row for cell address, Second row for previous value. Kind of like a
transaction log.
I'd recommend using Excel's built in Track Changes feature.
