Hi, I am trying to create an indicator of type number which gives me the sum of element A and B Minus element C. I will trigger a village once and get the number of Households and then check weakly if they have built a toilet.
Form A Yearly:- Elements :- Number of Households (Option Those with Toliets and Those without) -:--This element is taken during once but i will for the next 4 weeks check if those without toilets have built a toilet. Form b Weekly:- Element:- Number of HH that have built new toilet Hence my inidicator:- Balance of HH without toilets = Number of HH (Without toilets)-Number of HH that have built Toilets (Sum or aggregated over the weeks) The formula does not seem to get any result Cheers
