Unable to update multi-row

Question

Dear all,
I create a region with this information :
select
htmldb_item.hidden(1,QRY_IDS),
htmldb_item.hidden(2,SIT_ID),
SIT_ID SIT_ID_DISPLAY,
htmldb_item.checkbox(4,used_bl,decode(used_bl,'Y','CHECKED',NULL))used_bl,
dsc
from BSF_QRY_SITES qst,
bsf_sites sit
where sit.id = qst.sit_id and
qst.qry_ids = :p30_qry_ids
When I try to create to update my checkbox information it doesn't work.
Here the process to update it.
declare
t_use_bl char(1);
begin
for i in 1..htmldb_application.g_f01.count loop
t_use_bl := 'N';
for x in 1..htmldb_application.g_f04.count loop
if htmldb_application.g_f01(i) = htmldb_application.g_f04(x) then
t_use_bl := 'Y';
end if;
end loop;
update bsf_qry_sites
set used_bl = t_use_bl
where qry_ids = htmldb_application.g_f01(i)
and sit_id = htmldb_application.g_f02(i);
end loop;
end;
I take this example in the htmldb handbook.
Can someone help me please.
Thanks in advance
Eric

Hello,
Now I receive this error message when i try to update.
ORA-01722: invalid number
Now my select is :
select
htmldb_item.hidden(1,ids) ids,
qry_ids,
"SIT_ID" SIT_ID_DISPLAY,
htmldb_item.checkbox(2,used_bl,decode(used_bl,'Y','CHECKED',NULL))used_bl
from test_eric
and my process to update is :
declare
t_use_bl varchar2(1);
begin
for i in 1..htmldb_application.g_f01.count loop
t_use_bl := 'N';
for x in 1..htmldb_application.g_f02.count loop
if htmldb_application.g_f01(i) = htmldb_application.g_f02(x) then
t_use_bl := 'Y';
end if;
end loop;
update test_eric
set used_bl = t_use_bl
where ids = htmldb_application.g_f01(i);
end loop;
end;
Why I receive this error ?
I need to solve this problem to develop a new application. If I'm not able my user will ask to develop with an other tools.
Thanks in advance for your help
