I have a constant sum question, and the total should add up to 100 when respondents fill it out. I could set the validation to "must total" to force the response total to be 100, but in order to maximise participant survey completion rates, I don't want to force responses in my survey. Is there a way to generate some sort of a "request response" message if respondents click submit after incorrectly filling out the question (the total doesn't add up to 100)? I'm thinking of a message that appears once and gives respondents the option to return to the question to fill it out correctly, but also the option to just proceed to the next question.
