Database constraint and references

The answer I get is: You're missing the 'fk_genre_id' column. Can anyone tell me what is wrong with my code?

Here is the code:

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

Maria;

Here is what I have used, you are very close.

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

Happy coding,

Ken
