MySQL syntax error in the CREATE TABLE statement

SQL
query:

CREATE TABLE
            `comment_threads` (
 `comment_id` INT( 11 ) UNSIGNED NOT NULL DEFAULT
            '0',
 `updated` TIMESTAMP NOT NULL ,
 `timestamp` TIMESTAMP NOT NULL
            ,
) ENGINE = MYISAM
            ;

This is an old file
that I'm trying to run on HostGator through phpMyAdmin. I get an error that
says:

MySQL said: #1064 - 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 ')
ENGINE=MyISAM' at line
5

UPDATE:
If
I change the statement to this, I still get an
error:

CREATE TABLE
            comment_threads (
comment_id INT( 11 ) UNSIGNED NOT NULL DEFAULT
            '0',

updated TIMESTAMP( 14 ) NOT NULL ,
timestamp
            TIMESTAMP NOT NULL
PRIMARY KEY ( comment_id ) )
ENGINE = MYISAM
            ;

I get the
error:

ERROR 1064
(42000): 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 '( 14 ) NOT NULL
,

timestamp TIMESTAMP NOT NULL
