Stored procedure and ref cursor problem

Question

I am trying to create a stored procedure that can be used in Crystal Reports. To do this I have to create a package and a ref cursor. My SQL is below:
--Package
Create or Replace Package Test_Package
as type test_type is ref cursor;
end;
--Procedure
Create or Replace Procedure Test_Proc
(test_cursor in out test_package.test_type,
parameter in string
as
begin
open test_cursor for
select ClientName from apbpman.cv_client where clientref = parameter;
end;
--When trying to execute the SP in Oracle I use:-
set serveroutput on
declare
test_cursor apbpman.test_package.test_type;
resultset test_cursor%rowtype;
begin
apbpman.test_proc(test_cursor,'0096');
if not test_cursor%isopen then
dbms_output.put_line ('OK');
else
dbms_output.put_line ('Not OK');
end if;
fetch test_cursor into resultset;
while test_cursor%found loop
dbms_output.put_line(resultset.ClientName);
fetch test_cursor into resultset;
end loop;
end;
Whenever this runs I receive the following error reports:
resultset test_cursor%rowtype;
ERROR at line 3:
ORA-06550: line 3, column 13:
PLS-00320: the declaration of the type of this expression is incomplete or malformed

I have tried in vain to find a resolution to this but have failed. Please help.
Thanks,

Unless you are running a really old version of Oracle, any weak ref cursor can just be declared SYS_REFCURSOR. Also, you can't use a weak ref cursor for %ROWTYPE. You can test the procedure in SQL*Plus by using it to populate a refcursor variable.
