According to this Form Operators and Functions — ODK Docs
… functions are needed for accessing responses to questions inside repeat groups.
The sum(), max(), and min() functions offer access to numeric data, is there any way to access text response for the ENTIRE nodeset in a repeat group (NOT a specific indexed node using the indexed-repeat function)?
I am looking for a way to remove choices in a repeated question as they are available just once. Example: Resource A is assigned to user 1, resource C is assigned to user 2, resource B is assigned to user 3
Using the same select_one I would here want to remove resource A and C before I get to the iteration #3 in order to prevent the enumerator to assign the same resources to more than one user,
