I am pretty new to using Survey123 and I'm trying to set up a few hidden fields in my Survey 123 form but it keeps coming back with errors which I can't seem to fix. I am using Survey 123 Connect on my desktop to edit the spreadsheet.
1. Pulling data from a geopoint field to create hidden lat and long fields.
Type = hidden, name=lat, calculation= pulldata("@geopoint",${GPSLocation},"y") bind::esri@FieldType= esriFieldTypeDouble
Comes back with error:

The same error occurs for Longitude where I've used x instead of y.
2. Creating a group which just contains blank hidden fields that I can then edit at the back end of things once the survey has been submitted. I left the bind::esri@FieldType column blank as I read that the default was text which is what I want.
type = hidden, name= RespondedYN
Comes back with error:

I've attached my XLS sheet so that you can see exactly what I've done. Hopefully someone will be able to help.
Thanks in advance!
