How do i design a survey form in KoBoToolbox that sums with a constraint?

Hello Sir,

Please support me in the below points.

Calculation type Question

Q1. Total Male
Q2 Total Female
Q3. 6 Years to 18 Years (Not greater than Total Male/ Not greater than Total male and female)

Please explain with some examples.

Hi @sarbeswar,

Could you please explain your issue a bit more clearly. Q3 seems a bit unclear at the moment.

Have a great day!
