Validation Based on Previous Response

Support
1

Hi,

Is it possible to build in validation based on a previous response?

e.g. If the answer to "How old are you?" is 25, the validation range for
"How many years have you smoked?" would be 12-25, while the overall range
for the question might be 12-65.

Any suggestions/advice on this point would be greatly appreciated.

Best,
Audrey

Hi Audrey,
Yes, this is possible. Not sure if this is the most efficient way, but the
following seems to work for your use case.

  • add a constraint on age:".>= 12 and .<=100"
  • after age, you add a calculate question that calculates the maximum years
    smoked based on the age: "/constraint/age - 12" The user won't see this.
  • on the 'Years smoked' question, you add a constraint so the answer is
    than the max_years_smoked and less than 65: ".<=
    /constraint/max_years_smoked and .<= 65"
