How to run a report from Forms 9i

I want to run a report from Forms using Oracle 9i. For that i wrote the following script and created the report object named(REPORT6)

When i run the script by pressing a button , in  :agenti.nume( that is a text field in my form) is print repserver_116 (repserver is my Report Server). but , the report doesn't appear.I receive no other message.

declare
report_id Report_Object;
ReportServerJob VARCHAR2(100);
BEGIN
report_id:= find_report_object('REPORT6');
SET_REPORT_OBJECT_PROPERTY(report_id,REPORT_COMM_MODE,SYNCHRONOUS);
SET_REPORT_OBJECT_PROPERTY(report_id,REPORT_DESTYPE,CACHE);
SET_REPORT_OBJECT_PROPERTY(report_id,REPORT_SERVER,'repserver');
SET_REPORT_OBJECT_PROPERTY(report_id,REPORT_COMM_MODE,SYNCHRONOUS);
SET_REPORT_OBJECT_PROPERTY(report_id,REPORT_FILENAME,'C:\Licenta\test.rdf');
--SET_REPORT_OBJECT_PROPERTY(report_id,REPORT_OTHER,'p_deptno='||:agenti.id_agent||' paramform=no');
:agenti.nume:=run_report_object(report_id);
END;
