I have a form that has 22 drop down fields each having a value of 0-10 to choose from. Is it possible to have it add up the total value of those selected numbers and have it tally it up in another field at the end? So example: if each of the 22 fields were selected and the person clicked on the value 2, I would like it to add it up and give me the answer of 44 so I do not have to manually count each number in each of the fields.  Is it also possible to tally up how many drop down values were selected other than ZERO (example, if out of 22 fields, 10 were selected at 2, and 12 were selected as 0, then giving me the value of 10 would be a number I would also like to have added up)

This is for a concussion symptom form with 22 different symptoms each having a score of 0-10, so I would like my form to tell me how many symptoms were selected (outside of Zero) and tally up all the numbers that were selected.
