Select and functions

Hello all,

I am having a little bit of trouble here.

If I use the replace function in a select statement all works as expected.

select firstname, lastname, replace(worktelephonenumber, ' ', '') AS worktel
from contacts;

But if I use it in a before trigger the procedure fails to work.

CREATE OR REPLACE FUNCTION staging.write_work_country()
RETURNS trigger AS
'
DECLARE
alias_rec RECORD;
BEGIN
-- Clean the phone number
NEW.worktelephonenumber = REPLACE(NEW.worktelephonenumber,' ','');
RETURN NEW;
END;
'

I get the following error:

ERROR: parser: parse error at or near "','');

Can anyone help me please?

Thanks.

Stephen.
