What I’m trying to do: I have a form where the user can set a total land area that they own (say, 10 acres). A repeat group then lets them indicate how many acres they use per economic activity (say, 3 acres for farming and 7 acres for livestock). I’m trying to implement a constraint so that the sum of the individual plots cannot be greater than the total area initially indicated – see questionnaire XLSForm attached. TEST_Questionnaire.xlsx (16.8 KB)
Challenge: I cannot get the dynamic constraint to work based on the calculation because the [sum of individual plots] from the repeat group is initially empty. Does anyone have a solution for this?
Also, is it possible to implement a constraint so that within the repeat group, no select_one option is chosen more than once across the repeats?
