How to print a report which is consist a paper parameter form

Question

Hi !
I have created a report file with paper parameter form and also create a form. Now , when I try to run this form it display
REP-0788: Warning: The value of restricted LOV parameter ppass is not among the selectable values.
     USER ID     (a combo box with data)
     PASSWORD (a combo box with data)
After click on submit the query button window dispaly a message run successfuly,But it does not print the report's data, it prints only paper parameter contents.
i.e. REP-0788: Warning: The value of restricted LOV parameter ppass is not among the selectable values.
     USER ID     (a combo box with data)
     PASSWORD (a combo box with data)
I used the following codes
PROCEDURE RUN_REPORT1(vc_reportoj Varchar2, vc_reportserver varchar2, vc_runformat varchar2,report_otherparam VARCHAR2, pvar varchar2) IS
v_report_id Report_Object;
vc_ReportServerJob VARCHAR2(100); /* unique id for each Reportrequest */
vc_rep_status VARCHAR2(100); /* status of the Report job */
vjob_id VARCHAR2(100); /* job_id as number only string*/
vfilename varchar2(255);
vport varchar2(50);
hidden_action VARCHAR2(2000) :='';
v_report_other VARCHAR2(4000) :='';
i number (5);
c char;
c_old char;
c_new char;
BEGIN
/* Get a handle to the Report Object itself. */
v_report_id:= FIND_REPORT_OBJECT(vc_reportoj);
SET_REPORT_OBJECT_PROPERTY(v_report_id,REPORT_FILENAME,name_in(':parameter.path') ||'\'||NAME_IN('CTL_REPORTS.REPORT_NAME'));
     if pvar = 'FILE' then
          vfilename := CLIENT_GET_FILE_NAME('c:\',null, 'All Files (*.*)|*.*|',SAVE_FILE);
          if vfilename IS NOT NULL THEN     
          SET_REPORT_OBJECT_PROPERTY(v_report_id,REPORT_COMM_MODE,SYNCHRONOUS);
          SET_REPORT_OBJECT_PROPERTY(v_report_id, REPORT_EXECUTION_MODE, RUNTIME);
     SET_REPORT_OBJECT_PROPERTY(v_report_id, REPORT_DESTYPE, FILE);
               SET_REPORT_OBJECT_PROPERTY(v_report_id, REPORT_DESNAME, vfilename||'.rtf');
               SET_REPORT_OBJECT_PROPERTY(v_report_id,REPORT_SERVER,vc_reportserver);
               hidden_action := hidden_action ||'&report='||GET_REPORT_OBJECT_PROPERTY(v_report_id,REPORT_FILENAME);
hidden_action := hidden_action||'&destype='||GET_REPORT_OBJECT_PROPERTY(v_report_id,REPORT_DESTYPE);
hidden_action := hidden_action||'&desformat='||GET_REPORT_OBJECT_PROPERTY (v_report_id,REPORT_DESFORMAT);
hidden_action := hidden_action ||'&userid='||get_application_property(username)||'/'||get_application_property(password)||'@'||get_application_property(connect_string);
c_old :='@';
FOR i IN 1..LENGTH(report_otherparam) LOOP
c_new:= substr(report_otherparam,i,1);
IF (c_new ='') THEN
c:='&';
ELSE
c:= c_new;
END IF;
-- eliminate multiple blanks
IF (c_old ='' and c_new ='') THEN
null;
ELSE
v_report_other := v_report_other||c;
END IF;
c_old := c_new;
end loop;
hidden_action := hidden_action ||'&'|| v_report_other;
hidden_action := 'http://127.0.0.1:8889/reports/rwservlet'||'?_hidden_server='||vc_reportserver|| encode(hidden_action);
SET_REPORT_OBJECT_PROPERTY(v_report_id,REPORT_OTHER,'pfaction='||hidden_action||''||report_otherparam);
-- run Reports
               vc_ReportServerJob:=RUN_REPORT_OBJECT(v_report_id);
               vjob_id := substr(vc_ReportServerJob,length(vc_reportserver)+2,length(vc_ReportServerJob));
vc_rep_status := REPORT_OBJECT_STATUS(vc_ReportServerJob);
IF vc_rep_status='FINISHED' THEN
WEB.SHOW_DOCUMENT ('http://127.0.0.1:8889/reports/rwservlet/getjobid'||vjob_id||'?server='||vc_reportserver||'&_blank');
ELSE
message ('Report failed with error message '||vc_rep_status);
END IF;
ELSE
     RETURN;
end if;
This is the part of the procedure.
