Update collection

Question

I am new to htmldb and collections.....but something is just not clicking for me.
I have a collection created and it is populated correctly. I am trying to update a record (or is it called member??) in this collection.
The query to retrieve collection is:
select distinct htmldb_item.hidden(01,seq_id) seq_id,c001,c002,c003,c004, c005, c006,c007,c008,c009,s.common_name, r.last_name||', '||r.first_name Fisherman
from htmldb_collections,
permits p, participants r, species_qc s
where collection_name = 'ALLOCATE'
and c007 = p.permit_id
and p.participant_id = r.participant_id and
c006 = s.species_itis
order by fisherman
the process to update (multiple rows) the collection is:
declare
l_status varchar2(10);
l_cnt number;
l_county number;
begin
-- these records can only be updated. No new records can be added.
l_status := 'U';
select count(*) into l_cnt from htmldb_collections where collection_name = 'ALLOCATE';
FOR i IN 1..l_cnt LOOP
htmldb_collection.update_member_attribute(
p_collection_name => 'ALLOCATE',
p_seq => htmldb_application.g_f01(i),
p_attr_number => 5,
p_attr_value=> htmldb_application.g_f05(i) );
end loop;
I receive the following error:
ORA-20103: Member sequence 1641 does not exist in application collection "ALLOCATE"
the value 1641 seems to be refering to CATCH_SEQ (c004), not SEQ_ID.
Any help is appreciated!
thanks, Karen

Hi Vikas...thanks again for your time on this.
I am using DISTINCT because my earlier query was pulling in duplicates...of species.
I have created a new region, with the query SELECT * FROM HTMLDB_COLLECTIONS where COLLECTION_NAME = 'ALLOCATE'. It pulls up 2 records (as did the previous region) with SEQ_ID = 1 and 2.
I update the column C005 (reported quantity) and then press SAVE. The process UPDATE_COLLECTION runs and I receive an error.
declare
l_status varchar2(10);
l_cnt number;
l_county number;
begin
-- these records can only be updated. No new records can be added.
l_status := 'U';
select count(*) into l_cnt from htmldb_collections where collection_name = 'ALLOCATE';
FOR i IN 1..l_cnt LOOP
htmldb_collection.update_member_attribute(
p_collection_name => 'ALLOCATE',
p_seq => htmldb_application.g_f01(i),
p_attr_number => '5',
p_attr_value=> 100 );
end loop;
commit;
end;
error:
ORA-20103: Member sequence 1521 does not exist in application collection "ALLOCATE"
once again, 1521 refers to the value in C003 or the collection. hmm.
I am certain that this will be an obvious fix...but have been looking at this for the past couple of weeks with no resolve.
thanks again!
