I have created another tab on my xls form and labeled it "external_choices" to hold several cascading select options.
In this tab, the headers are the same as my "choices" tab.
In my "survey" tab, I have referenced this tab using the question type "select_one_external [list_name]".
However, each time I attempt to update the form, I get the error: "List name not in choices: [list_name]".
I have also tried different name variations for the "external_choices" tab such as "external_select", "external_selects", and "external_choice". All of these have produced the same result. Am I missing something? Or is there another way to source my cascading select questions from the external_choices tab?
