Once again, thank you for the code. I've had a little more time to study it now, and it works very well. Now, I also understand what you meant in your first reply.

Thank you for that code. The solution you've found is exactly the one I was hoping to find.

I'm not familiar with the method you're using (map), but it looks as if you make a guess on the "values" that should make out Du. Is this correct?
