I have 4 columns with choice field type. Each column has 1,2,3,4,5 value . Now if I select value from each column and submit it should add up those number. If some other user login and do the same thing it will add up the numbers with the previous user's total. Incase user changes the value then it should not add up with the existing one whereas it should add up only the changes.
I need some logic/code to achieve this using JSOM
