I had 2 other threads here yesterday and found answers, but we still need.
Need to code for the ActiveCell in the 1st line of
Private Sub SeeDiff() .. below.

TIA - Bob

Snippets from the 2 other threads from yesterday...
I'm going to run this code in Workbook_Open instead of Worksheet_Change (it
does work in Worksheet_Change). We've decided the Excel file will be
essentially only a "snapshot" as all data will be maintained in the Access
Database.

So..Workbook_open will include code for each of the 72 Cells, IE...
Range("DNine").Select
Call SeeDiff
Range("ENine").Select
Call SeeDiff
.....

Private Sub SeeDiff()
Set t = Application.Caller <---No "Target" here...how do I set the
"ActiveCell"?
.....I tried Application.Caller & Application.ThisCell suggested in this
thread by Chip...
....but that didn't work............................
