Calculations not working

I have multiple sections on my form and within each section I have two sets of radio options with values assigned to the choices. I am using the the form calculator widget to very simply add the two values together however the issue I have is in the Person 2 and Person 3 etc that the radio buttons need to be clicked in the correct order to be able to get a value to appear in the calculated field. What have I done wrong?
