Help with calling packages from crystal reports

Question

hi I am trying to call a package from crystal reports, but geting an error
Failed to open a rowset
4200:datadirect:odbcdriver:odbc oracle driver: unrecognised escape sequence.
im sure its somthing realy stupid im doing wrong any ideas????
the command in crystal is
{CALL  Enhanced_Pharos_Report.run_report
(NVL({?var_detail_id},0))}
the package, which works as a stand alone object is
----------spec------------------
create or replace package Enhanced_Pharos_Report
AS
TYPE result_set_type IS REF CURSOR;
PROCEDURE run_report
(var_detail_id NUMBER, v_Media_Object_Name out varchar2);
end;
-----------body-----------------------
create or replace package body Enhanced_Pharos_Report as
v_Media_Object_Name varchar2(300);
function Media_Object_Name(var_Detail_id Number) return varchar2 as
Result varchar2(300);
begin
SELECT promo_name
INTO Result
FROM promo
WHERE promo_id = (SELECT promo_id
FROM promo_plan
WHERE promo_plan_id = (SELECT promo_plan_id
FROM event_promotion
WHERE detail_id = var_Detail_id));
return(Result);
end Media_Object_Name;
PROCEDURE run_report
(var_detail_id NUMBER, v_Media_Object_Name out varchar2)
is
begin
v_Media_Object_Name := Media_Object_Name (var_detail_id);
end;
end;
