Dear community,I would like to add a 'not applicable' option to a Constant Sum question. What I have now is this:Where I ask every participant to indicate their language preference per domain. However, it might be that this domain is not applicable to the participant (e.g. they don't go to school) so I want them to have the option to say 'not applicable'. Right now, I used a temporary fix by asking them to fill in 100 points on 'not applicable' ('niet van toepassing' in Dutch) but this doesn't seem like a very elegant solution. Does anyone know how to make this more user-friendly? Maybe there is a code I can use?Thanks in advance! Elise

Elisabethan ,Glad to know it helped! 😃If I have understood this correctly, your custom validation should be added to the 'not applicable' question such that -if the constant sum is answered, 'not applicable' is not selected ORif the constant sum is not answered, 'not applicable' is selected.Following custom validation on the 'not applicable' should help you achieve this:

Elisabethan - I get it now. Maybe you can add a multiple-choice multi-select option with a 'Not Applicable' option below the constant sum question. You can use CSS to reduce the space between the two questions so that it looks like one question. Additionally, using custom validation you can make sure that either the constant sum question or the checkbox is answered at a time.
