I've collected quite a bit of data and have realized that a good portion of it is systematically missing (only part 2 of the survey). When I look at the data it says "The question was not displayed to the respondent." I've checked my display logic and I've run myself through the survey and everything seems fine. I've also duplicated this survey and the data for the duplicated survey is not missing. I am wondering if anyone can explain why this is the case and hopefully recover this data. I am almost sure that the participants completed these questions because the group with "missing data" took just as long as those who do not have missing data.
