Do CommCare Auto Case Closure case property filters overrule the Case Close field (days since updated)

One way to accomplish this is by loading the label text in a hidden variable's Calculate Condition and then reference that variable later.

Create a hidden variable with your label text

Add the label text to the Calculate Condition of a hidden variable question type. For example, my_label_text

Reference that variable in a question's label text box

You can drag and drop that hidden variable, my_label_text, into the label portion of the question:

Save the hidden variable to a case property

You can then add logic to save my_label_text as a case property in the Case Management tab. In your scenario you may also want to add logic to save whether or not the question was answered properly.

If you're filtering cases, you want an expression that ultimately returns a set of cases. The first part of the expression, instance('casedb')/casedb/case, gives you all cases on the phone.

The expressions in square brackets then filter the cases by case type, parent (you're limiting to cases that are children of the "current" case, which is the one you selected from the case list), and open/closed.

[@case_type='Indicators']
[index/parent=current()/@case_id]
[@status='open']

The /[contractions_dur = 'low'] is what's throwing the error. The / says to go another level deep, but I suspect what you want is to just add the contractions_dur as a fourth constraint, on the same level as the others. So try dropping the slash: instance('casedb')/casedb/case[@case_type='Indicators'][index/parent=current()/@case_id][@status='open'][contractions_dur = 'low']
