Missing data (NA) underneath some variables

Question

Dear all,
Some of my columns were completely missing when I downloaded the collected data. When I changed variables setting to ”Any data stored in the data set, including those from deleted questions/items” now I see the missing columns but WITHOUT data (NA) underneath the columns in my CSV file. However, these variables (questions) haven’t been deleted at all. And right now on pretest mode I see the questions and I have answered them (these are mandatory questions so no one could skip answering them).
Why are the data missing underneath some of the must to answer columns? I have read the section about ”Problem Solutions for Data Retrieval” and have tried the suggestions but still cannot solve the problem! would you please help me figure out the solution?

Best,

Why are the data missing underneath some of the must to answer columns?

There are several possibilities:

1) People may have stopped answering on that page or before -> check LASTPAGE

2) People may have completed another questionnaire -> check QUESTNNR

3) You may not have included the respective questions in your questionnaire -> check Compose Questionnaire

4) You may have renamed the variables -> check the question

5) You may have change the question time from "selection" to "multiple choice selection"

6) An error may have occured during data import -> check Collected Data -> View Data
