I have a survey with several ranking questions and then a final question that allows the user to rank only the top ranked choice from previous questions. For each question, I calculated the first selection, "question1_1st", using "selected-at(${question1},0)" in the calculation field of the XLS form. Then, for the final question, used a choice filter to only display the top choices (in the choice_filter field, "name=${question1_1st}").
The first 14 ranking questions work just fine on all platforms; however, some users have reported that they are unable to rank the options in the final question with the choice filter. All issues have occurred on Android mobile devices.
Has anyone else run into a similar problem or have any suggestions to mitigate this issue?
