If the routine that Gord provided started with
Sub Worksheet_...
or
Private Sub Worksheet_...

Then it goes into the worksheet area which is easily accessible: right
click on the worksheet's name tab and click the [View Code] option in the
list. Copy and paste the code into the module that appears.

Is there a way to lock a cell in a shared workbook after the user has made an
