SELECT INTO returns incorrect values

[Bill Todd <pg@xxxxxxxxxx>]

The following SELECT INTO returns incorrect values in the variables 
CATEGORY_NAME and PARENT_ID. If I copy the SELECT statement to pgAdmin, 
delete the INTO clause and run the query it returns the correct values. 
I am new to PostgreSQL and I must have something syntactically wrong in 
the SELECT but I can't see what it is. Any suggestions?

DECLARE
 PARENT_ID BIGINT;
 CATEGORY_NAME VARCHAR(40);
BEGIN
     SELECT CATEGORY, PARENT_CATEGORY_ID
     INTO CATEGORY_NAME, PARENT_ID
     FROM NOTE.CATEGORY
     WHERE CATEGORY_ID = 477;
     RAISE NOTICE 'CURR CAT, NAME, PARENT ID: % % ', CATEGORY_NAME, 
PARENT_ID;
END;
$BODY$
 LANGUAGE 'plpgsql' VOLATILE

Thanks,

Bill
