How can i make a conditional question where if a respondents refuses to answer, the survey ends?

Hi @mohammedrezeq,

You could do this as outlined in the image below:

In the survey tab of your xlsform:

In the choices tab of your xlsform:

Data entry screen seen in Enketo: If the respondent wishes to continue the survey

Data entry screen seen in Enketo: If the respondent does not wish to continue the survey

Reference xlsform:
Skipping Questions (End Survey).xlsx (10.8 KB)

Have a great day!
