Always consider the question type.
Single: there is only the question
Array, multiple: there is the question with subquestions in one dimension
Array(text), array(numbers: there is the question with subquestions in two dimensions.
If you are not sure, activate a small test survey, enter some data and have a look at the answer table.
BTW:
I did this by using the "{questionID}"
I suppose you used the "questionCode", not the "questionID"
