Error importing a previously exported mysql trigger - mysql

Question

I had a mysql trigger that has been working, I exported it and removed it and am trying to put it back, but I keep running into the following error:
#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 '' at line 12
My trigger is:
CREATE TRIGGER `accounts_tracking` AFTER UPDATE ON `accounts`
FOR EACH ROW BEGIN
IF( NEW.`check_level` != OLD.`check_level` ) THEN
INSERT INTO `accounts_tracking` ( `change_type`, `account_id`, `field`, `old_int`, `new_int`, `old_time`, `new_time` )
VALUES
( "1",
OLD.id,
"check_level",
OLD.`check_level`,
NEW.`check_level`,
UNIX_TIMESTAMP(),
UNIX_TIMESTAMP());
END IF;
END
Line #12 is the 2nd UNIX_TIMESTAMP()
My table structure is as follows:
CREATE TABLE `accounts_tracking` (
`id` int(10) unsigned NOT NULL AUTO_INCREMENT,
`change_type` smallint(5) unsigned NOT NULL,
`account_id` int(10) unsigned NOT NULL,
`field` varchar(255) NOT NULL,
`old_int` int(11) NOT NULL,
`new_int` int(11) NOT NULL,
`new_time` int(10) unsigned NOT NULL,
`old_time` int(10) unsigned NOT NULL,
PRIMARY KEY (`id`),
KEY `account_id` (`account_id`)
) ENGINE=MyISAM DEFAULT CHARSET=latin1;
Server type: MySQL
Server version: 5.1.73-log
Thanks.

As barranka suggested in comments section, you need to enclose this trigger in a delimiter, like so:
DELIMITER $$
CREATE TRIGGER `accounts_tracking` AFTER UPDATE ON `accounts`
FOR EACH ROW BEGIN
IF( NEW.`check_level` != OLD.`check_level`) THEN
INSERT INTO `accounts_tracking` ( `change_type`, `account_id`, `field`, `old_int`, `new_int`, `old_time`, `new_time` )
VALUES
( "1",
OLD.id,
"check_level",
OLD.`check_level`,
NEW.`check_level`,
UNIX_TIMESTAMP(),
UNIX_TIMESTAMP());
END IF;
END$$
DELIMITER ;
The reason is that by adding a Begin and End to the statement you are essentially creating a stored routine/procedure with the trigger itself. In order to run multiple statements, like in stored routine/procedure, you need to add delimiters.
In other cases where you do not have the Begin and End within the trigger, you do not need the delimiters. For Example:
CREATE TABLE account (acct_num INT, amount DECIMAL(10,2));
CREATE TRIGGER ins_sum BEFORE INSERT ON account FOR EACH ROW SET #sum = #sum + NEW.amount;
