SQL issue on task, constrain foreign keys?

Hi, The task is asking me to do this:

Alter the "t_movies" table to add a foreign key called "fk_genre_id" and constrain it to reference the "t_genres" "pk_id".

Here is my code:

ALTER TABLE t_movies ADD COLUMN fk_genre_id, ADD CONSTRAINT FOREIGN KEY (fk_genre_id) REFERENCES (pk_id);

Any idea's why the task keeps rejecting my code and saying "Bummer! You're missing the 'fk_genre_id' column."?

Thanks,

Adam
