Claus,

Hi, thank you for responding. Yes, that is a technique which works quite fine in Excel. However, as this task is to be done over & over again, and on many hundreds, perhaps thousands of rows, each time it is done, I would think that something a bit more automated might be more efficient.

However, I appreciate you providing an excellent, and correct way of performing the Average just by using Excel's built-in commands.

Thanks!
