Contradictory answers

[Zhomart]

Hello!!! I have a question. The questionnaire has multiple choice answers. But among them there are answers that contradict each other. How to make it so that there would be a warning when choosing contradictory answers?

@Zhomart, maybe this post discussed previously should help you solve your issue:

How do i create a form that restricts users to select certain choices?

Hi @sarbeswar, You could do it as outlined in the image shown below: In the survey tab of your xlsform: [Image 1] Data entry screen as seen in Enketo: No error message seen when select-able choices are selected. [Image 2] Data entry screen as seen in Enketo: Error message seen when choices are selected beyond the select-able choices.
