Now recreate the MEMBERS table with the new FAVORITE_ROCK_ID column, and make sure it has a foreign key constraint to the ID column of the ROCKS table. The columns should now be: ID, FIRST_NAME, LAST_NAME, and FAVORITE_ROCK_ID.
CREATE TABLE members
(
id int NOT NULL PRIMARY KEY,
first_name varchar NOT NULL,
last Name varchar NOT NULL,
FAVORITE_ROCK_ID int,
foreign key(FAVORITE_ROCK_ID) REFERENCES ROCKS(ID) );
Error is making sure to add foreign key Constraint

(
ID int NOT NULL PRIMARY KEY,
FIRST_NAME varchar NOT NULL,
LAST_NAME varchar NOT NULL,
FAVORITE_ROCK_ID int,
CONSTRAINT MEMBERS_ROCKS_FK FOREIGN KEY (FAVORITE_ROCK_ID)
REFERENCES ROCKS(ID)
);
I dunno why but it still doesn't work? I tried to change it including the last name but the error says: Bummer: Don't forget to add the foreign key constraint to the FAVORITE_ROCK_ID column.

FAVORITE_ROCK_ID int REFERENCES ROCKS(ID)
