Question

I have forms and report services 10.2.0.2 installed on my Win2003 server.
Reports runs perfectly with paramform=no but when i use paramform=yes it show html param form but pressing submit query it show The page cannot be displayed page. the same report with paramform=no and hard coding paramter runs perfectly.
This is the procedure i am using after adding hidden_action i start getting REP-52007 instead of the page cannot be displayed.....
PROCEDURE show_report(pRptServer varchar2,pRptObj varchar2,pRptFormat varchar2,pRptPath varchar2,pRptParameter varchar2,pParamForm varchar2) IS

     v_runformat varchar2(50):= pRptFormat;
     hidden_action varchar2(1000);
     v_report_other VARCHAR2(4000) :='';
begin
               repid := FIND_REPORT_OBJECT(pRptObj);
               SET_REPORT_OBJECT_PROPERTY(repid,REPORT_FILENAME,pRptPath);
               SET_REPORT_OBJECT_PROPERTY(repid,REPORT_COMM_MODE,SYNCHRONOUS);
               SET_REPORT_OBJECT_PROPERTY(repid,REPORT_DESTYPE,CACHE);

               v_rep := RUN_REPORT_OBJECT(repid);
               vjob_id := substr(v_rep,length(v_reportserver)+2,length(v_rep));
               rep_status := REPORT_OBJECT_STATUS(v_rep);
               while rep_status in ('RUNNING','OPENING_REPORT','ENQUEUED')
               loop
                    rep_status := REPORT_OBJECT_STATUS(v_rep);
               end loop;
               if rep_status = 'FINISHED' then
                    WEB.SHOW_DOCUMENT('/reports/rwservlet/getjobid'||vjob_id||'?server='||v_reportserver||'','_blank');
                    message('Finished');
