trigger updating a master table from detail table

this code doesn't compil any idea ?
EVENEMENT is a détail table of ETABLISSEMENT.

CREATE TRIGGER DATE_MAJ_ETAB_EVENEMENTS
  AFTER DELETE OR UPDATE OR INSERT ON EVENEMENT FOR EACH ROW WHEN (OLD.NUM_ETAB IS NOT NULL)
BEGIN
  UPDATE ETABLISSEMENT SET DATE_MAJ_ETAB = SYSDATE   WHERE NUM_ETAB = OLD.NUM_ETAB
END
;
