I know this is an old thread but would like to take it back since we´re experimenting a similar issue in DHIS2 2.31
The expression we´re using is as follows
The DE we´re using are Yes/No. The context of this indicator is related to a questionnaire with compulsory questions. All responded (yes/no) are considered in the numerator, while in the denominator only those responded, excluding those that for a logic in the questionnaire have been hidden - null)
any thought why the expression does not work properly?
