How do you build a 'relevant' for a multiple-choice question?

Hello everyone. I use this line of code ${id_activity_1_1}<=1019 in the ‘Relevant’ to show or hide a question in the form I build; the question id_activity is multiple, and when I select more than one option, the question is hidden. How should the ‘Relevant’ be built? . Please

Welcome @celkristi,

  • For select_multiple, you always need to use selected(…). See Form Operators and Functions - ODK Docs
  • All choice names are stored as strings.
  • Multiple choices are stored in a string, separated by one space. So, you cannot directly use a mathematic comparison like <= .
    So, it will be: selected($}YourSelectMultipleName}, ‘Value1’) or selected($}YourSelectMultipleName}, ‘Value2’) …

There is also a more complex option using the max() function…

General hint: Don’t forget, please, to check your form with the Online validator during development and before deployment. The Help Center articles and the search function of this form can often provide help and examples.

Thanks, the new relevant is this one, it works perfect for me.
selected(${id_activity_1_1}, ‘1011’) or
selected(${id_activity_1_1}, ‘1012’) or
selected(${id_activity_1_1}, ‘1013’) or
selected(${id_activity_1_1}, ‘1014’) or
selected(${id_activity_1_1}, ‘1015’) or
selected(${id_activity_1_1}, ‘1016’) or
selected(${id_activity_1_1}, ‘1017’) or
selected(${id_activity_1_1}, ‘1018’) or
selected(${id_activity_1_1}, ‘1019’)
