Dynamic query in reports region(multiple condition)

Question

Hi I have this sql query in the report region. And everytime I will run the report and choose to put a value on :P3_REQUESTID and the rest of the variables to null.It doesnt display the report.The same goes to other variables except for :P3_OOTSELECT.
If I choose to put a value on :P3_OOTSELECT and the rest to null, thats the only time that report will be displayed.
What am I missing here?
SELECT req_id,
order_no,
cust_nm,
cust_req_type,
entered_by,
alt_ref,
decode(cnt_rfs,null,null,'Yes')RFS,
rec_id
FROM oot_curr_stats
WHERE (trunc(create_dt,'MONTH') like :P3_OOTSELECT OR
trunc(create_dt) between to_date(:P3_FROMDT,'dd/mm/yyyy') AND to_date(:P3_DATETO,'dd/mm/yyyy'))
AND req_id like '%'||:P3_REQUESTID||'%'
AND sla_tag like :P3_SLATAG
Thanks,

It doesnt display the report.
What do you mean by that? The report query doesn't execute? Or it does execute and shows "no data found" or something?
If you "choose to put a value on :P3_REQUESTID and the rest of the variables to null" then this part of the predicate won't match any rows (I'll replace the null bind variables with null):
(trunc(create_dt,'MONTH') like null OR
trunc(create_dt) between to_date(null,'dd/mm/yyyy') AND to_date(null,'dd/mm/yyyy'))
Then you AND that with other terms but by then it's too late.
Perhaps I misunderstood.
