Udpate Insert (inside a LOOP)

Hey There,

I am trying to do an udpate or insert but it does not seem to work and I beleive it is because i am inside a LOOP. Here is the code. I need help please.

nBLANK NUMBER := NULL ;

BEGIN

SELECT INPUT_ID.nextval
INTO nBLANK
FROM qualstat_month;

admin_tokenizer.tokenize(sLIST_JOBKNOW,oListJobkno wToken,nTokenCount);
admin_tokenizer.tokenize(sLIST_CALLQUAL,oListCallq ualToken,nTokenCount);
admin_tokenizer.tokenize(sLIST_ORDQUAL,oListOrdqua lToken,nTokenCount);
admin_tokenizer.tokenize(sLIST_INPUT_ID,oListInput idToken,nTokenCount);

FOR i IN 1..nTokenCount LOOP
sJOBKNOW := to_char(oListJobknowToken(i));
sCALLQUAL := to_char(oListCallqualToken(i));
sORDQUAL := to_char(oListOrdqualToken(i));
sINPUT_ID := to_char(oListInputidToken(i));
IF sINPUT_ID IS NULL THEN
EXIT;
END IF;

UPDATE table2
set job_know = sJOBKNOW,
call_qual = sCALLQUAL,
ord_qual = sORDQUAL,
modified_date = sysdate,
modified_by = sLoginId
where input_id = sINPUT_ID;

IF nBLANK IS NULL THEN

INSERT INTO table2
(call_qual, ord_qual, job_know, input_id, modified_date, modified_by)
VALUES
(sCALLQUAL, sORDQUAL, sJOBKNOW, sINPUT_ID, sysdate, sLoginId);

END IF;

END LOOP;
