How to resolve "ORA-01403: no data found"

Question

When i attempt to delete from a table on which an after delete trigger is defined, i get exception as follows;
OracleException was unhadled by user code:
ORA-01403: no data found
ORA-06512: at "...TRIGGER_KATILIMEKLE", line11
ORA-04088: error during the execution of trigger '...TRIGGER_KATILIMEKLE'
Here is my trigger:
Note: Before i added block -ELSIF DELETING THEN- it was working fine, yet now it throws that exception somehow. Since i am not new to oracle, i just couldn't figure out. Thanks...
CREATE OR REPLACE TRIGGER TRIGGER_KATILIMEKLE AFTER INSERT OR DELETE ON IHALE_KATILINANIHALEDETAY
REFERENCING NEW AS newRow
FOR EACH ROW
DECLARE
srktkodu number;
ihlkodu number;
BEGIN
IF INSERTING THEN
select t2.srktkodu, t2.ihlkodu into srktkodu,ihlkodu from ihale_katilinanihale t2 where t2.detaykod=:newRow.detaykod;
INSERT INTO ihale_katilimcilar t (t.aktif, t.SRKTKODU,t.ihlkodu,t.ihlaltktgkodu) VALUES('0', srktkodu, ihlkodu, :newRow.IHLALTKTGKODU);
ELSIF DELETING THEN
select t2.srktkodu, t2.ihlkodu into srktkodu,ihlkodu from ihale_katilinanihale t2 where t2.detaykod=:newRow.detaykod;
DELETE FROM ihale_katilimcilar t WHERE t.srktkodu=srktkodu and t.ihlkodu=ihlkodu and t.ihlaltktgkodu=:newRow.IHLALTKTGKODU;
END IF;
END TRIGGER_KATILIMEKLE;

REFERENCING NEW AS newRow
ELSIF DELETING THEN
...=:newRow.detaykod;Please read about [url

Row Triggers in the manual.Thanks a lot.
Using REFERENCING NEW AS newRow and OLD AS oldRow and ...=:oldRow.detaykod; I handled it, however it just doesn't assign other parameters in delete query, thus it deletes only when t.ihlaltktgkodu=:oldRow.IHLALTKTGKODU; in the delete query and ,gnore the rest.
Although i assign the values of the parameters -srktkodu,ihlkodu- and make an successfull insert in the insert query, i just cannot in the delete. Why?
Right here :
select t2.srktkodu, t2.ihlkodu into srktkodu,ihlkodu from ihale_katilinanihale t2 where t2.detaykod=:oldRow.detaykod;
DELETE FROM ihale_katilimcilar t WHERE t.srktkodu=srktkodu and t.ihlkodu=ihlkodu and t.ihlaltktgkodu=:oldRow.IHLALTKTGKODU;
