I am creating a survey that has a lot of external csv choice lists. Some lists only have a few rows, some have ~90 rows. When I create a report, these values appear blank..
Does the report syntax need to change if the type is select_one_from_file? I could not find any documentation about this.
I had just tested with some basic data and was not able to reproduce the same behavior. The syntax should be no different you would just specify the question name with a dollar sign and curly brackets like a normal select_one question.
On the data tab in the Survey123 website do you see data for your select_one_from_file questions in the table?
