I've a CSV file with a list of ID numbers. What I'd like to do is to read the column ID from the CSV and load all the values in a "select_one" combo on my form in Survey123.
I know how to read the CSV file using "pulldata" function and "calculate" field in my XLSForm to retrieve values according to a key, but in this case there is no key: I just want to load a list of data reading an external file, instead of copying all the data in my "choice" sheet of the XLSForm. I've tried using pulldata in "constraints" field but without success....
Any ideas? Thanks a lot
