SQL Report with 1 updatable column - help urgent

Question

Hi,
I have a SQL report. I am using collection to store value of selected record by link column.
I have a updatable text item (NULL) in the column. I am able to store that value in the collection.
Any clue?
Code
1. Creating a collection in parent page:
apex_collection.create_or_truncate_collection
(p_collection_name => 'ORDER');
2. Query to populate item rows with option to key 'QTY' before pressing 'Add to Order' link.
select
itemcode,
description,
NULL AS qty,
'Add to Order' add_to_order
from itemtab
3. Made 'QTY' to Text item -- to allow users to key value
4. Created 'hidden & protected' items P1_ITEMCODE, P1_QTY
5. Set values of itemcode, qty in add_to_order link
6. Created a process to add values into collection:
for x in (select * from itemtab where itemcode = :P1_ITEMCODE)
loop
apex_collection.add_member(p_collection_name => 'ORDER',
p_c001 => x.ITEMCODE,
p_c002 => x.DESCRIPTION,
p_c003 => :P1_QTY
end loop;
7. Display value of itemcode, description, qty in report region
select c001, c002, c003
from apex_collections
where collection_name = 'ORDER'
Probem: The value of qty is not being stored in the collection and not appearing in the #7 report. itemcode and description values are fine.
Thanks,
Dip

Dip,
I'm guessing here as I can't see your application, I think your missing the page process to collect the data from your QTY field.
I created a quick demo of what i think your trying to achieve on apex.oracle.com
http://apex.oracle.com/pls/apex/f?p=19923:2
I added this to the html expression on the report Field add to:
<input type="button" onclick="doSubmit(#RANDOM_ID#)" value="Add To" />
Then the page process to collect and set the page item:
DECLARE
l_qty number;
BEGIN
FOR i in 1..APEX_APPLICATION.G_F03.COUNT LOOP
l_qty := nvl(APEX_APPLICATION.G_F03(i),0);
IF l_qty > 0
THEN
:P2_QTY := l_qty;
:P2_RANDOM_ID := :REQUEST;
EXIT;
END IF;
END LOOP;
END;
Let me know if this helps
