[Juan Martinez]

Hy, Im doing the next:
DELIMITER $$
CREATE DEFINER=`root`@`%` PROCEDURE `EpisodiosProcedure`(IN EPIS_ID INTEGER)
BEGIN
DECLARE txn_error INTEGER DEFAULT 0 ;
DECLARE CONTINUE HANDLER FOR SQLEXCEPTION
BEGIN
SET txn_error = 1;
END;

SAVEPOINT EPISAVEPOINT;




INSERT INTO sene3_visitas_ant
(AVISI_ID,
AVISI_AEPIS_ID,
AVISI_FAMI_ID,
AVISI_NOMBRE,
AVISI_FECHA,
AVISI_HORA_LLEGADA,
AVISI_HORA_SALIDA,
AVISI_OBSERVACIONES,
AVISI_ACTIVO,
AVISI_FECHA_MOD,
AVISI_USUA_MOD)
SELECT VISI_ID, VISI_EPIS_ID, VISI_FAMI_ID, VISI_NOMBRE, VISI_FECHA,
VISI_HORA_LLEGADA, VISI_HORA_SALIDA, VISI_OBSERVACIONES, VISI_ACTIVO,
VISI_FECHA_MOD, VISI_USUA_MOD
FROM sene1_visitas
WHERE sene1_visitas.VISI_EPIS_ID = EPIS_ID;
SELECT 'INSERT INTO sene3_visitas_ant OK' ,concat(' ' , txn_error);



IF txn_error > 0 THEN
ROLLBACK TO EPISAVEPOINT;
SELECT 'INSERT INTO aborted ' ,concat(' t ' , txn_error);
ELSE

DELETE FROM sene1_visitas WHERE sene1_visitas.VISI_EPIS_ID = EPIS_ID;


IF txn_error THEN
ROLLBACK TO EPISAVEPOINT;
SELECT 'DELETE aborted ';
ELSE
SELECT 'OK';
END IF;
END IF;
END $$

MYSQL says: Error Code : 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 'DELIMITER $$. Why?
Thanks
