Changing Cases of Strings: Code Challenge 2 Trouble

The Complete Challenge 2 Statement: The library is generating new library cards that will display the full name and their library ID. The full name needs to have the last name in all caps. Create a report with two columns of results, one is an alias of full_name the second being the library_id.

My code seems to produce the wanted results according to the directions:

SELECT first_name || ' ' || UPPER(last_name) AS "full_name", id AS "library_id"
FROM patrons;

however, I get an error: Expected results to look like "Andrew CHALKLEY", "MCL1001" not "Alena HOLLIGAN", 3. However, the library ID number is only 1 digit long (1, 2, 3, 4). So I'm not sure if the challenge is missing some information on something I'm to be doing with the id or if I'm missing something that's explained more clearly than I think it is.... Can anyone offer advise? Thanks!

The patrons table includes a column for library_id.

:point_right: Return the library_id column directly instead of aliasing the name of the id column.

This is an example of one of those times where I was staring at the problem too long, and I wasn't able to think of what was wrong. Thanks for providing the outside assist I needed!
