Hello, this is my first post and I am really in need of help. I tried many hours searching for an answer without finding one so please forgive me if this has been covered before. I have windows 10 on an old Gateway laptop and version 4.3.1 of Oo. I run a little game that tracks how well players are able to pick winners of American Football (N.F.L.) games. On my last sheet, Year to Date, I would like a formula that would count the number of weeks that someone has picked 10 or more winners. l thought that "countif('week 1'.A1:'week 17'.A1;=>10)" would do it, but no. I get an error code 510 and I'm lost. I've been able to self teach myself everything else but this has me stumped. PLEASE HELP.
Thank you.
