Can't see what's wrong with this function?

I am trying to create a function but I don't get further than this and something is already wrong...
The function so far look like this..:

CREATE OR REPLACE FUNCTION getNettoHastighet (INTEGER) RETURNS INTEGER AS '
DECLARE
ordreid_val ALIAS FOR $1;
tmprec RECORD;
opplag integer;
total bigint;
total_hour float;
hastighet integer;
BEGIN
select into tmprec (extract(epoch from sum(Til - Fra)) * 1000.0) as total from Log_stop where OrdreID = ordreid_val and StopType = 1;
total := tmprec.total;
return 0;
END;
' LANGUAGE 'plpgsql';

I get the following error if I try to create the function..:

[Error Code: 0, SQL State: 42601] ERROR: syntax error at or near "$1"

Any hints on what's wrong?

Regards,

BTJ
