No error, but error?

Nice job with the error testing chalkers. I have the output exactly correct -- verbatim yet I can't pass the task. Let's get a slow clap going here. Error message below.

"Andrew CHALKLEY", "MCL1001" not "Andrew CHALKLEY", "MCL1001".

Part 1:

SELECT 
  LOWER(title) AS lowercase_title, 
  UPPER(author) AS uppercase_author
FROM books

Part 2:

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

You forgot to show your query code to allow us to make an accurate diagnosis.

But often, when the error message indicates that your output looks like what is expected, the problem might not be in the data but in the column names. Check for a possible misspelling of the alias names assigned to the columns.

It seems that checkbox is currently not functioning because this is the second time I've opened a ticket where it didn't include the code.

Anytime that happens, just type it into the question, or add it using a comment.
