This is an error message when you have a select_one vo4lq95 or a select_multiple vo4lq95 in the survey sheet in row 552 but you don’t have the respective choices under the choices tab for this question. As a quick check, you could press CTRL + F and then type vo4lq95 under the survey sheet and see that the question is there. Similarly, you could press CTRL + F and then type vo4lq95 under the choices sheet and see that the list_name vo4lq95 is missing there.
Solution, you will have to provide the list_name, name, and label for the missing question. That should solve your issue. Please also be informed that once you fix this you should re-check your xlsform through the online validator to see if there are any other syntax issues within your xlsform. You will need to repeat this cycle until you fix the issue.
