Using MYSQL Triggers and Foreign Keys - mysql

Question

I do not know how to handle my issue here and I am looking for the most practical solution. I have to track a user-id across multiple tables and I am looking at triggers and Foreign Keys to solve the initial inserts into the databases for each user. On registration, I would like to create a row in each database with the user id. That way its always an update statement when I reference it in the code.
Here is my Table Structure
CREATE TABLE `authentication` (
`userid` int(11) unsigned NOT NULL AUTO_INCREMENT,
`fname` varchar(11) COLLATE utf8_unicode_ci DEFAULT NULL,
`lname` varchar(11) COLLATE utf8_unicode_ci DEFAULT NULL,
`email` varchar(50) COLLATE utf8_unicode_ci NOT NULL DEFAULT '',
`password` varchar(11) COLLATE utf8_unicode_ci DEFAULT NULL,
`online` int(11) DEFAULT NULL,
`created_at` varchar(11) COLLATE utf8_unicode_ci DEFAULT NULL,
PRIMARY KEY (`email`),
KEY `userid` (`userid`)
) ENGINE=MyISAM AUTO_INCREMENT=5 DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci;
CREATE TABLE `user_progress` (
`userid` int(10) NOT NULL,
`progress_event` varchar(25) COLLATE utf8_unicode_ci DEFAULT NULL,
PRIMARY KEY (`userid`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci;
Here is an example trigger I tried to make
CREATE TRIGGER user_progress_add
AFTER INSERT ON authentication
FOR EACH ROW
BEGIN
INSERT INTO user_progress (userid, progress_status)
VALUES (NEW.userid, 'signup');
END
This trigger did not work. It gives the error "You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'END' at line 1".
I guess my question is, whats wrong with my trigger? is a trigger a better idea in this case than a foreign key?
