Calculating total sum value within a repeat group

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_members5}+{No_of_hhld_with_10_members10}
How can I go about this
