I keep getting "type does not exist" on compile of this SETOF function (list 2 table)

[CODE]

BEGIN;

DROP TYPE structure.format_list2table_rs CASCADE;

CREATE TYPE structure.format_list2table_rs AS (
"item" VARCHAR(4000)
);

END;

CREATE OR REPLACE FUNCTION structure.format_list2table (
"v_list" varchar,
"v_delim" varchar
)
RETURNS SETOF structure.format_list2table_rs AS
$body$
/*
select * from Format_List2Table('1', '1');
SELECT item FROM Format_List2Table('first||2nd||III||1+1+1+1','||');
SELECT CAST(item AS INT) AS Example2 FROM
Format_List2Table('111,222,333,444,555',',');
SELECT item FROM Format_List2Table('12/1/2009, 12/2/2009, 12/3/2009,
