How to call (in PL/SQL) a Procedure with a VARRAY OUT parameter

Question

Please help, I always get this error:
PLS-00306: wrong number or types of arguments in call to 'GET_ITEM'
It's a simple procedure, what is wrong?
create or replace
package XXVDF_XPOS_NEW_SALE_TEST as
     type serial_nos               is varray(200)     of     varchar2(20);
procedure get_item
(P_SERIALS           IN serial_nos);
end XXVDF_XPOS_NEW_SALE_TEST;
create or replace
package body XXVDF_XPOS_NEW_SALE_TEST as
procedure get_item
     (P_SERIALS          IN serial_nos)
is
begin
     p_serials(1) := 'sdw';
end get_item;
end XXVDF_XPOS_NEW_SALE_TEST;
declare
     type serial_nos               is varray(200) of     varchar2(20);
     P_SERIALS          serial_nos := serial_nos();
begin
null;
     XXVDF_XPOS_NEW_SALE_TEST.get_item(P_SERIALS);
     dbms_output.put_line('P_SERIAL_NUMBERS ' ||P_SERIALS(1));
end;
thanks, Steve White

Correction those INs should say OUT:
create or replace
package XXVDF_XPOS_NEW_SALE_TEST as
     type serial_nos               is varray(200)     of     varchar2(20);
procedure get_item
(P_SERIALS           OUT serial_nos);
end XXVDF_XPOS_NEW_SALE_TEST;
create or replace
package body XXVDF_XPOS_NEW_SALE_TEST as
procedure get_item
     (P_SERIALS          OUT serial_nos)
is
begin
     p_serials(1) := 'sdw';
end get_item;
end XXVDF_XPOS_NEW_SALE_TEST;
declare
     type serial_nos               is varray(200) of     varchar2(20);
     P_SERIALS          serial_nos := serial_nos();
begin
null;
     XXVDF_XPOS_NEW_SALE_TEST.get_item(P_SERIALS);
     dbms_output.put_line('P_SERIAL_NUMBERS ' ||P_SERIALS(1));
end;
========
XXVDF_XPOS_NEW_SALE_TEST.get_item(P_SERIALS);
