Good morning to everyone! I have a Pro plan subscription and i am wondering whether i can use/ edit formulas in cell/column. When i right click, the option to edit formula is visible in the pop up menu, but is not enable.

Should i upgrade the subscrition? i just want to add a simple column "Progress", allowing user to select from specific values 0%, 25%, 50%, 75% , 100% and next a another column "Status" in which i will have the formula, "Completed" when Progress == 100% and Not completed when Progress< 100%
