Super simple pie chart

I think the reason it wasn’t showing up was really stupid because it is starting to work now. I had removed all the formatting like I usually do and just noticed my preview wasn’t blank, it had a feint thin vertical line, lol fixed formatting and that fixed it. that’s embarrassing. now it only shows the label if I hover. one more question… any idea how to get the label to just show?

thank you so much for all the help, you also confirmed the right way of writing the expression, which was sooo frustrating for me, lol.
