I want to control a text field if it is empty like for example : /data/my_field <> “”. I would like find a better expression of comparing an empty field. This is to control the require text field with my own message
In CommCare you check if a field is empty by checking if it is equal to the empty string, so:
/data/myfield = ''
true if the field is empty, and
false if it is non-empty
Thanks Aliza for your support
