Those stored templates won't work in the template tester because they require an argument, the column name. That is why I supplied the template searches, which provide the needed argument to the stored templates.
You can also test the stored templates using the "Test" button in the Stored template dialog, but it isn't much of a test as it looks at only the currently selected books. For example, it you press the Test button and enter
Code:
get_one_book_per_field_value('authors')
you will see a 1 or an empty string for each book.
