A simple newbie question with select

I have following table and a stored procedure in which I want to select rows from the table whose LOCAL_ID is one of the ids I give
it in a_local_ids table which is input parameter and return them via cursor in/out parameter.

It should be called as:
local_ids := local_id_array(1, 2, 3, 4, 5); call mappings_find_remote_ids(1, local_ids, remote_ids_ref)

How can I write that since statement below yields this error: ORA-00932: inconsistent datatypes: expected NUMBER got SYSTEM.LOCAL_ID_ARRAY. Hope you understood the question, excuse my poor english. Thank you in advance, Tomy.

CREATE TABLE SYNCML_MAPS (
  IDN_ID NUMBER(11) DEFAULT 0 NOT NULL,
  LOCAL_ID NUMBER(11) DEFAULT 0 NOT NULL,   REMOTE_ID VARCHAR2(32) NOT NULL,
  UNIQUE(IDN_ID, LOCAL_ID),
  UNIQUE(IDN_ID, REMOTE_ID),
  FOREIGN KEY(IDN_ID) REFERENCES SYNCML_IDNS(ID) ON DELETE CASCADE
);

CREATE OR REPLACE TYPE local_id_array AS TABLE OF NUMBER(11);

PROCEDURE mappings_find_remote_ids (

    a_db_idn IN SYNCML_MAPS.IDN_ID%Type,
    a_local_ids IN local_id_array,
    a_remote_ids IN OUT data_cursor

      OPEN a_remote_ids FOR SELECT local_id, remote_id FROM SYNCML_MAPS
          WHERE idn_id = a_db_idn AND local_id IN a_local_ids;
