Why can't I see the hidden values I assigned to my radio buttons in the calcluation wizard?

I've added values to my radio buttons and now I want to create a place for the sum total of those values. When I click on the Form Calculation, those values do not show up as fields in the calculator. What am I missing?

Never mind!
