Code fault and pivot fault?

Question

SET SERVEROUTPUT ON
       declare
    sonuc float;
    begin
      SELECT AVG(GPA_RESULT)
       into sonuc FROM (
       SELECT  oa.ogrenci_no,sum(n.sayisal*dt.kredi)/sum(dt.kredi+0.00000000000001)  GPA_RESULT 
         FROM ders_aktif da,ders_tanim dt,ogrenci_akademik oa,ders_kayit dk, notlar n
         WHERE
                da.acildigi_yil=2007 and
                oa.ders_baslama_yil=2007 and
      oa.birim like '1521%' and
      (da.acildigi_donem='1'or
      da.acildigi_donem='2')and
      da.ders_kodu like '1521%' and
      (dt.normal_yariyili=1 or
      dt.normal_yariyili=2)and
      dt.ders_kodu=da.ders_kodu and
      da.acilan_ders_no=dk.acilan_ders_no and
      oa.ogrenci_no=dk.ogrenci_no and
      dk.harf_kodu is not null  and
      dk.y_yil is null and
      dk.harf_kodu=n.tanim and
      n.ortalamaya_kat='1' and
      dk.durum='1' and
      dk.yerine is null AND
      dk.yil<=2007
      group by oa.ogrenci_no);
       dbms_output.put_line('GPA lerin ortalaması='||sonuc);    
     end;the above code is running correctly. and the result is
sonuc
GPA lerin ortalaması=2.5078663284036687778981464598173228276 9I dont want to these only da. acildigi_yil is 2007 year . I want to the last 5 year 2007,2006,2005,2004 .
I prepared codes with using pivot but has error acout da.acildigi yil .

PL/SQL: ORA-00904: "DA"."ACILDIGI_YIL": invalid identifierSo ı couldnt do using pivot because of error.
create or replace
