It sounds like you are describing one field for each criteria? If so, it will work a lot better if you establish one RECORD per criteria and simply count records. What is the value of the radio button; is it 'yes' or 'no' or '1' and '0'?
If you can switch to records instead of fields (and we'd help you through the switch and it TRULY is the wise way to go) then you would simply count the records. :^)
the radio buttons are set as yes or no. i am not sure if i understand with the records suggestion. i have listed how i currently have it set up:
(Student Name) (Criteria 1) (Criteria 2) (Criteria 3) (Criteria 4) (Number of Criteria completed)
There are radio buttons for each of the criteria. I am hoping to set up a calculation so that the last field can determine how many criteria have been met by each student. The number of criteria would then generate a grade. does your suggestion with the records per criteria allow me to do the same thing? i am in the midst of trialling the best set up so i am happy to try different things to get the best option
