It's not clearly understood on applying multiple conditions to alphabetize names in a query. Any advice?

As the code attached demonstrates, I don't quite comprehend what needs rectified to make this legible SQL.

I don't understand how not adding a comma makes this work, in my mind the following makes sense but does not take: [...] ORDER BY last_name ASC, ORDER BY first_name ASC LIMIT 20 OFFSET 60;

If guidance could be offered, I'd be most grateful. Thank you!

You only use ORDER BY once, then list the conditions separated by commas:

ORDER BY last_name ASC, ORDER BY first_name ASC  -- so instead of this
ORDER BY last_name ASC, first_name ASC           -- do this
