Error in SQL challenge

Hi,

I can't see what is wrong with my query. I tested the same code in the SQL Playground and got a fine result with other names for the book authors. Now i have replaced the names with the names from the challenge, but gets an error saying that it is expecting two rows and that i should check the names.

Am i doing anything wrong?

Now we're in the e-commerce database. In the users table we have the columns id, username, password, first_name and last_name.

Find all users with either the last name "Hinkley" or "Pettit"

Query: SELECT * FROM users WHERE last_name = "Hinkley" OR "Pettit";

Result: Bummer: Expecting two rows, please check that you are checking for both names and they are correct.
