I've got a grid of cells filled with either a 'y' or an 'n'.
I'd like to work out the percentage of the 'y's.
So I need a formula that's something along the lines of:
Out of this selection, divide number of 'y's by 'y'+'n' x 100.
So I know what I need but not how to write it 😅
Any help much appreciated - thanks!
