What is wrong with this TRIGGER?

[Alberto Alcázar Martín]

Hi,
I think this trigger is okey, I rewrote it several times but always came out the same 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 6<<
(As I changed the trigger the line changed)

This is the trigger:
"
CREATE TRIGGER SEVEN_re_insert
AFTER INSERT ON ps_customer
FOR EACH ROW BEGIN
IF NEW.recargo_eq=1 THEN
INSERT INTO ps_customer_group (id_customer,id_group)
VALUES(NEW.id_customer,4);
END IF;
END;
"

P.S.: of course I've checked examples and reference manuals.

Thank you all, regards.
