Additional Information

This is an expected behavior for the web form because Math functions (except number()) only work with number values. For more details, refer to https://docs.opendatakit.org/form-operators-functions.

Workaround

Use the join() or concat() function to connect strings. For example, join(",",${who_hugged}).
