...
I know that in Access, I can cause things to happen when a field has been
changed. I want to do something similar in Excel. If any cell in a given
column (G) changes, I want a macro to run that will force the user to
enter
data in another cell.
How do I make one of these "after update"- type things happen?

TIA
