Welcome to the community, Wendy! :grinning_face_with_big_eyes: If those category values are going to remain fixed, this would probably be easier to bake them into a formula, rather than pull them from a second table. (The latter is doable, but baking them is much easier.)
Here’s a quick example I threw together:
![Screen Shot 2019-05-06 at 5.12.38 PM.png Screen Shot 2019-05-06 at 5.12.38 PM.png](/t5/image/serverpage/image-id/3473i5784DF44809DA169/image-size/large?v=v2&px=999)
The formula for the {Value Pts.}
field is this:
((100 - (Value - 1) * 20) / 100) * 40
For the others, just replace “Value” with the new category field name, and the final number with the max for that category.
Does this get you what you want?
