Fetch PB

Question

Hello everyone,
I am working on a PL/SQL query that should return a variable number of lots. The PB is that in some cases my function works and in other it returns a PL/SQL error.
Is there a problem with my data or is the function not taking every case into account ?
Here is the function in question:
function find (pc_co char, pn_project number, pn_ctrlnum number, pn_seqnum
number, pn_surveyor number, pn_minutenum number) return varchar2 is
lc_complete_lot varchar2(4000):='LOT ';
lc_lot varchar2(16):= null;
ln_lot number(2):= 0;
v1 number(2):= 2;
cursor c_count_lot is
select count(distinct lot)
from lot
where co = pc_co
and project = pn_project
and ctrlnum = pn_ctrlnum
and seqnum = pn_seqnum
and surveyor = pn_surveyor
and minutenum = pn_minutenum
and lotflag = 'Y';
cursor c_lot is
select distinct (lot)
from lot
where co = pc_co
and project = pn_project
and ctrlnum = pn_ctrlnum
and seqnum = pn_seqnum
and surveyor = pn_surveyor
and minutenum = pn_minutenum
and lotflag = 'Y';
begin
--open c_count_lot;
--fetch c_count_lot into ln_lot;
--if nvl (ln_lot,0) > 0 then
--     select count(lot) into v1 from lot;
open c_lot;
for i in 1..v1 loop
fetch c_lot into lc_lot;
if i > 1 then
lc_complete_lot := lc_complete_lot||', ';
end if;
lc_complete_lot := lc_complete_lot||lc_lot;
end loop;
--close c_count_lot;
close c_lot;
--end if;
return lc_complete_lot;
end find;
