Report with parameter form

Question

I am trying to run the report from menu with the following code
declare
repid REPORT_OBJECT;
v_rep VARCHAR2(100);
rep_status VARCHAR2(50);
BEGIN
repid := find_report_object('test');
SET_REPORT_OBJECT_PROPERTY(repid, REPORT_FILENAME, :global.user_dir||'test.REP');
if id_null(repid) then
     pause;
     message('repid is null');
     else
SET_REPORT_OBJECT_PROPERTY(repid,REPORT_EXECUTION_MODE,BATCH);
SET_REPORT_OBJECT_PROPERTY(repid,REPORT_COMM_MODE,SYNCHRONOUS);
SET_REPORT_OBJECT_PROPERTY(repid,REPORT_DESTYPE,CACHE);
SET_REPORT_OBJECT_PROPERTY(repid,REPORT_DESFORMAT,'pdf');
SET_REPORT_OBJECT_PROPERTY(repid,REPORT_SERVER,'repsrv');
SET_REPORT_OBJECT_PROPERTY(repid,REPORT_OTHER,'paramform=yes');
end if;
v_rep := RUN_REPORT_OBJECT(repid);
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'||substr(v_rep,instr(v_rep,'_',-1)+1)||'?'||'server=repsrv','_blank');
ELSE
message('Error when running report');
END IF;
END;
The report parameter form displays
and when i enter the values
gives me the error
REP-52007: Parameter form format error.
