When we create a survey in odk build, is there the option of conditioned questions that allow you, depending on the answer go to the end of the form?
Its easy to condition questions based on previous responses using excel. I advise you to save your form in Xls format then present here how u want your questions flow. We will be able to help.
Thanks William solved the problem using the relevant function relevant="(selected(/data/have_children, 'yes'))"
