OK THIS IS WEIRD

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

ALTER TABLE t_movies 
      ADD COLUMN fk_genre_id INTEGER NULL,
     ADD CONSTRAINT FOREIGN KEY (fk_genre_id) REFERENCES t_genres(pk_id)

I dont think if i am doing any thing wrong but its giving me an error ? any ideas
