Maybe if you wish to use a cascading select with an external file you could follow the instructions discussed in our previous post (this should solve your issue):

Hi @Giuliano, So looking at your requirement, you could design your xlsform as outlined below using select_one_from_file and select_multiple_from_file: In the survey tab of your xlsform: [Image 1] In the choices tab of your xlsform: [Image 2] In the csv file: [Image 3] Data entry screen as seen in Enketo: [Image 4] Reference xlsform: select_one_from_file.xlsx (16.4 KB) Reference csv file: School_Code.csv (44.0 KB) Have a great day!

Have a great day!
