Yes, I'm still using xl 2019. As a very limited excel connoisseur, and a from time to time user, I'm not very familiar with PIVOT TABLES and LARGE functions ... I will deepen my knowledge of both functions and and make some attempts ... but I'm afraid this will not be of any help for my need right now! I'm not pretending that someone else does my homework for me ... in a longer o shorter period of time I will be surely able to do it myself ... but presently, if some moral principles do not inhibit it, an immediate and satisfactory help would receive a due appreciation! In any case, whatever the outcome, thank you very much, friends.

You may learn better by watching a short video, as I generally do.

This looked pretty straightforward to me.
