2 Aktions in a Rule

Hello,
I hope someone can help me. I Want 2 Aktions executeed in a Rule like:
CREATE RULE auftraege_neu_delete AS ON delete
TO auftraege_neu DO
(DELETE FROM auftraege_neu_positionen
WHERE auftraege_neu_positionen.auftragsnr = OLD.auftragsnr;
DELETE FROM auftraege_neu_zubehoer
WHERE auftraege_neu_zubehoer.auftragsnr = OLD.auftragsnr;);
but I get a Parser Error:
ERROR: parser: parse error at or near ""
This is in PostgreSQL 6.5.2

Has anyone the correct syntax?

regards
Florian
