No worries! I just like to be absolutely sure, because I’ve seen a lot of fringe cases in excel that really make you think hard about how you’re going to lay everything out. I just wanted to be sure before I worked on it. I love Excel, though, and wouldn’t have minded doing it over lol.
The formulas in my other reply should absolutely work. Let me know if you need help with that!
Also, I’d definitely be interested in a “Libre/OpenOffice help” group. I think it’s fun finding creative and clean ways to solve things that seem difficult.
