I'm trying to create a foreign key on two columns but getting error...

Here's what I tried:

CREATE TABLE test2 (
ID INT NOT NULL AUTO_INCREMENT,
col1 INT NOT NULL,
col2 INT NOT NULL,
PRIMARY KEY (ID),
CONSTRAINT fk FOREIGN KEY (col1, col2)
REFERENCES test1(ID, ID)
ON UPDATE CASCADE
ON DELETE RESTRICT
) ENGINE=InnoDB;

But I get `ERROR 1005 (HY000): Can't create table 'DB.test2' (errno: 150)`
