In a fishing questionnaire, interviewers have to choose a frequency (in % or with categorics assignated to values, named “percent_zone”) of a geographical area (roster named “engin_zone”) drawn by them, for each fishing tool (roster named “engin”).
So to have coherent numbers, i have a calculated variable (named “percent_zone_sum”) which make the sum of these answers
engin.SelectMany(y=>y.engin_zone). Select(x=>x.percent_zone). Sum()
And a validation condition for this question :
With this message when the total is not equal to 100 %
The sum is not equal to100 % but %percent_zone_sum% %
This perfectly works on designer, but on the Interviwer App, the variable seems not work, with ‘[…] %’ instead of the number calculated, and the validation is never completed.
