Additions and callback
I have three numeric questions which if I add the three answers, I want it not to exceed 100%. and if it exceeds, it cancels what was answered in the three questions and force the user to fill in the correct answers again. e.g.
I trade in Mangoes, Coconuts and Aples. I need to apportion the %age loss for Mangoes in Q1, %age loss for Coconuts in Q2 and %age loss for Aples in Q3 . If I add the three losses, It should not exceed 100%. I want to restrict the respondent from proceeding to another set of questions untill he / she fills in the three losses figures whose total shall not exceed 100%.
