Select the "first_name" followed by the username in parentheses and alias it as "display_name". For example "Andrew (chalkers)". There's a space between the end of the first_name and username in parentheses.
My query is below.

Found the errors on period ( . ) that should be comma ( , )
SELECT CONCAT(first_name, " (", username, ")") AS display_name FROM users;
I also find the String Function video @2:05 that seems hard to see clearly whether period or comma, however it is very common to use comma in SQL Databases.
Hope that helps.
