Cascading file

Hello,
I have created a cascading file. The commune (commune) depends on the department (département), and the department depends on the region (region).

I would also like to create 2 variables: Surveyor and Supervisor. Both must depend on the region, such that there are 2 surveyors per region and 1 supervisor per region.
The surveyors are coded from 1 to 4, and the supervisors are coded from 1 to 2.

How can I add these 2 variables (surveyor and supervisor)?
The file in attached.

Thank you

@nohandoye, if you have not gone through it, then this support article Adding Cascading Select Questions should help you design a cascading select question.

In addition, this community post discussed previously should also help you understand how it’s built through the XLSForm:
