Survey123 Report Template Error when checking

[phess_luckstone]

Hey Everyone,

I get an error when making my report template, I want to list/order all of the selected records in a report like this:

Whenever I use: ${#survey|orderByFields:"objectid DESC"|resultRecordCount:3}${objectid}

It works for the object ID but if I change to ${outfall_number}, it messes up. And throws this error.

Currently my report has this but doesn't work 

${#survey|orderByFields:"outfall_number"|result RecordCount:20}${outfall_number}

Any help would be amazing!
