I want to set the validation criteria of a numeric question to not be greater than the numeric response of a previous question. If I understand correctly, you identify the question by putting the name within ${} but then how do you say that the response has to be <= the response of the previous question?
I need to manually enter the validation logic in XLSForm Code as I am working with KoboCollect for this survey. I don't think this is super complex, but I'm new to this.
Thank you!
