Calling PL/SQL package (that returns a table) from a package

I am trying to call a PL/SQL package (that returns pl/sql tables) from a pl/sql package. When I try to compile the body it errors with "PLS-00306: wrong number or types of arguments in call to 'CALLED_PKG'". The reason I am using pl/sql tables is to pass customized record sets to a VB program. This works. I can call the package correctly from VB but not from another PL/SQ package.

here is the pacakges i created to test. Calling a package without a pl/sql table works.

CREATE OR REPLACE PACKAGE eva_test_calling_pkg IS

   TYPE tbl_cust_order_id IS TABLE OF sysadm.customer_order.id%TYPE

      INDEX BY BINARY_INTEGER;    PROCEDURE call_table_pkg (

      p_cust_order_id OUT tbl_cust_order_id    );    

   PROCEDURE call_varchar2_pkg (

      p_cust_order_id out varchar2    );
END eva_test_calling_pkg;
/

CREATE OR REPLACE PACKAGE BODY eva_test_calling_pkg AS

   PROCEDURE call_table_pkg (p_cust_order_id OUT tbl_cust_order_id)    IS

      pp_cust_order_id tbl_cust_order_id;    BEGIN
   null;

      eva_test_called_pkg.called_pkg(pp_cust_order_id );    END call_table_pkg;

   PROCEDURE call_varchar2_pkg (p_cust_order_id OUT VARCHAR2)    IS

      v_cust_order_id sysadm.cust_order_line.cust_order_id%TYPE;    BEGIN
      eva_test_called_pkg.called_varchar2_pkg(p_cust_order_id);    END call_varchar2_pkg;
END eva_test_calling_pkg;
/

CREATE OR REPLACE PACKAGE eva_test_called_pkg IS

   TYPE tbl_cust_order_id IS TABLE OF sysadm.customer_order.id%TYPE

      INDEX BY BINARY_INTEGER;    PROCEDURE called_pkg (

      p_cust_order_id OUT tbl_cust_order_id    );
   PROCEDURE called_varchar2_pkg (

      p_cust_order_id OUT varchar2    );
END eva_test_called_pkg;
/

CREATE OR REPLACE PACKAGE BODY eva_test_called_pkg AS

   PROCEDURE called_pkg (p_cust_order_id OUT tbl_cust_order_id)    IS

      TYPE tbl_act_cost_ratio IS TABLE OF NUMBER
         INDEX BY BINARY_INTEGER;

      v_cust_order_id     sysadm.cust_order_line.cust_order_id%TYPE;
      p1_act_cost_ratio   tbl_act_cost_ratio;
   BEGIN
      p_cust_order_id (1) := 10;
      p_cust_order_id (2) := 11;

   PROCEDURE called_varchar2_pkg (p_cust_order_id OUT VARCHAR2)    IS

      v_cust_order_id VARCHAR (30);
   BEGIN
      p_cust_order_id := 'OK';
   END called_varchar2_pkg;
END eva_test_called_pkg;
/

I get the following error when I compile:
