HELP: what's wrong with my PL/PSQL function??

hello!

i have the following function:
CREATE FUNCTION plusSum(text,int4) RETURNS int4 AS '
DECLARE
jrlname ALIAS FOR $1;
sumup ALIAS FOR $2;
actsum int4;
arow RECORD;
conversion float8;
temp float8;
sum float8;
BEGIN
sum := 0;
RAISE NOTICE ''stats % '', sumup;
FOR arow IN SELECT * FROM "jrlname" WHERE plus=sumup LOOP
SELECT conv FROM currencies WHERE tag=arow.currency INTO conversion;
sum := sum + (arow.amount/conversion);
END LOOP;
return round(sum);
END;
' LANGUAGE 'plpgsql';
select plusSum('journal','102');

and i get an error:
ERROR: parser: parse error at or near "$1"
(BTW would be helpful if the thing could spit out also the line
number....)

isolated the prob to this line:
FOR arow IN SELECT * FROM "jrlname" WHERE plus=sumup LOOP
in fact it doesn't seem to like the fact that i use a dynamic table
name??

i remind vaguely that pl/psql had indeed this sort of problem... but
this was years ago.... is there any workaround? even using perl?

The whole prog is a bookkeeping program... and i want it now really able
to work with several sets of tables.... without duplicating also the
functions i wrote associated to the tables....

BTW is there a possibility to make further select calls out of plperl?
(an example making this would come in handy...)

i am using a postgres7.03 DB on a debian system...
