PL/pgSQL Syntax Problem

Hi,

this function:

CREATE FUNCTION t_nummern(integer) -- Parameter: lfd_nr
RETURNS text AS '
DECLARE
lfd_nr ALIAS FOR $1;
erg text;
daten record;
BEGIN
erg := '''';
FOR daten IN
SELECT * INTO daten FROM telefon WHERE t_lfd_nr = lfd_nr
LOOP
IF erg <> '''' THEN
erg := erg || '', '';
END IF;
IF daten.t_einrichtg <> '''' THEN
erg := erg || daten.t_einrichtg || '': '';
END IF;
erg := erg || ''('' || daten.vorwahl || '') '' || daten.telefon_nr;
END LOOP;
RETURN erg;
END;'
LANGUAGE 'plpgsql';

causes the following error:

mitglieder=> select t_nummern(330);
ERROR: query "SELECT * INTO daten FROM telefon WHERE t_lfd_nr = $1 "
isn't a
SELECT
mitglieder=>

Why isn't this a SELECT??

Thanks in advance,
