Hi @amaglior,
Just from your explanation, I have a feeling this is a standard household listing questionnaire mostly applicable for malaria net use studies. If that is the case, I would suggest a different workaround for your questionnaire where the three parameters are not entered directly by the interviewer but rather through a different form design where the calculation is done directly from the household roster. Can you please send your XLS form I have a look at it and recommend an alternate solution?
