Hi Kal_Lam

I am trying to calculate the sum of the number of households mapped with a specific number of people for each family size

That is the number of respondents who come from a family of 5, 10 to obtain the total number of persons mapped

I had tried this but I keep getting an error when I try and deploy the form

sum(${No_of_hhld_with_5_members*5}+{No_of_hhld_with_10_members*10}

How can I go about this
