Setting up Yes/No data element

Dear DHIS2 users,

I am setting up a questionnaire with Yes/No value. When creating the data element, I have choosen the “Yes/No” Value Type. I expect to have a “1/0” value as output. After entering data in the questionnaire, there is no value appearing from the data vizualiser. Could you please send a link of a step-by -step guide on creating the Yes/No value? I am using DHIS2 2.19.

I appreciate your support.

Tantely.
