Hi

In the network with a shared Excel file with 10 simultaneous users, I
would like to give a warning to a certain user when someone else
changes something in a column with his/her name, and saves the file.
Concerned person can easily see the change when looking at the shared
file, but there is normally other work going on and a warning would be
needed to "wake up" and react to the change. Warning could be like a
msgbox "There is a task opened for you", which you must "ok".

Any great ideas how to solve this?

Regards, Jari
