SQL & PL/SQL

Hi ,
I've written the trigger in the following format.. As the original trigger is around 700 lines, so just format is written here.. please co-operate..

 CREATE OR REPLACE TRIGGER --
AFTER UPDATE OF COL1
ON TAB1
REFERENCING NEW AS NEW OLD AS OLD
FOR EACH ROW
WHEN (NOT(OLD.COL1 IS NULL AND NEW.COL1=0))
DECLARE
 --
 --
rowToins PAK1.fdList;
i number;
BEGIN
 IF :NEW.COL2='V' THEN
 INSERT INTO DEST(
  ---
  ---
  D_AT)
 SELECT * FROM ( SELECT --
   ----
   ----
   PAK2.FUN1('AD',TAB10.ID) AS D_AT
 FROM ---
 WHERE --- )
   WHERE D_AT IS NOT NULL;
ELSEIF :NEW.COL2 ='H' THEN
 SELECT * FROM ( SELECT --
   ----
   ----
   PAK2.FUN1('AD',TAB9.ID) AS D_AT
 BULK COLLECT INTO rowToins
 FROM ---
 WHERE --- )
   WHERE D_AT IS NOT NULL;

 i:=rowToins.FIRST;
 WHILE i IS NOT NULL LOOP
 --insert row 1
  PAK1.fun2(rowToins(i).<col>,
  ----
  );
 i:=rowToins.NEXT(i);
 END LOOP;
END IF;
END;
/

The above code is giving the error..

PL/SQL: ORA-01744: inappropriate INTO

So how can i correct the code...

thanks
