Good day

How does one get to set limits on an open ended numeric question on KoboCollect?

These would be, for example, a question that accepts a minimum of 5 and a maximum of 30.

Regards
Thulani

Go to settings (in the numeric questions) and in Validation Criteria field click on Manually enter your validation logic in XLSForm code and paste this code

string-length(.) >= 5 and string-length(.) <= 30

I was checking the code again and realize that when the integer is larger than 16 digits, kobo automatically converts it in an exponential number.

So, my recommendation is to create a text question and instead the code I gave you up; use this one
regex(., '[0-9]') and string-length(.) >= 5 and string-length(.) <= 30

what this code does is to restrict the field only to accept numbers and also restrict the length

Regards,

K.

Thulani, are you seeking to restrict the number of digit (length) if the answer, or just that the number provided has to be between 5 and 30?

Hi Thulani,

  1. You need to first add a question and select the 'number' as question type.
  2. Once the question is added, you need to edit the question settings - click on the cogwheel on the top right corner of the question box.
  3. The settings option will appear with a menu bar on the left with three options - Question Options / Skip logic / Validation criteria
  4. Select Validation Criteria
  5. Select 'add a condition'
  6. Enter the condition using the signs and values you want - you will have the option to add multiple conditions, and make sure to select that the question must meet all the criteria specified. Your screen should look like the attached.
