Odd Validation Rule Check

Users
1

Hi All,

I have a form in which I want users to be guided by certain validation
rules but I also have some "special" cases that I want to allow.
As an example, for an age question, I want to validate age to be between 18
and 100 years, but also want the ability to enter something like -65 for
non response or -77 for dont know.
Is this possible or is there another work around?

Kind regards,

Hi Sam,

Most of the time we try to support those workflows using structured
validation rather than "key" inputs.

For Example:

Question List:

  • "What is the person's Age?"
    • id: age_input
    • Validation Condition: 18-100
    • Display Condition: age_unknown = ''
  • Multiple Select Question with no Text
    • id: age_unknown
    • Age is Unknown - value -77
  • Hidden Value
    • id: age_output
    • calculation: if(../age_unknown = -77, -77, if(age_input = '', -65,
      -77)))

That will give you the output of 18-100, -77, or -65 from the hidden value
"age_output", but will give your users the ability to enter either a valid
age, check a box that denotes that the age is unknown, or skip the question
without needing to know the special flags.

whoops, wrote that expression a bit fast. I meant:

  • calculation: if(../age_unknown = -77, -77, if(../age_input = '', -65,
    ../age_input)))

Thanks Clayton

An if statement in the validation seems to work also.Something like if((.

= 18 and . <= 100), true(), if((. = -65), true(), if((. = -77), true(),
false())))
Question: Does having a number of these (100 or more) affect the load speed
of the form?

Kind regards,

Sam,

Encoding in the validation condition definitely works as well, yes.

Including validation conditions will have a marginal impact on the speed of
loading the form. At that scale I would not anticipate a meaningful hit to
performance.
