Thanks for the tip. However, somehow it works differently with me! Here's what I did:
1. Opened the VBA editor (Press Alt+F11)
2. Inserted a new module (Insert > Module)
3. Copy/Pasted the user defined function LastSaved as shown here.
4. Left the VBA editor (Press Alt+Q)
At first, it displayed: 06.06.2007 and a time value. I then saved, closed and re-opened Excel. The function seemed to work. Now, it is stuck at this other value: 30.10.2007 12:55:22! And no matter what I do, the same value is shown. What have I done wrong?
I am using English Excel on a German machine.
