Update database using check boxes

Question

I have a query region that produces a checkbox and an associated line with the checkbox. The data in the database that is a "Y", produces a checked box.
select check_box_seq,
htmldb_item.checkbox(1,is_it_checked,decode(is_it_checked,'Y','CHECKED')) D,
check_box_text R
from check_box_tbl
What I need to happen is to change one or more check boxes. I have a MultiRow Update process, with a process point of On Submit - After Computations and Validations with a PL/SQL conditional processing of:
FOR I in 1.. HTMLDB_APPLICATION.F_F01.COUNT LOOP
update table check_box_tbl set is_it_checked = Y
where check_box_seq = htmldb_item.application.g_f01(i);
END LOOP;
But the data in the database does not change. I have read numerous discussion on this thread but I have not found exactly what I need or can not recognize it.
How can I get the data in the database to change when I either change a checked box or after I have changed all boxes and then press the SUBMIT.

Answer 1

I am having a similar problem that I cannot find the answer to. (See my process below). I don't think that the process is "grabbing" the checked values in the SDN column. It is using NULL, so therefore no rows are being inserted in the table. Shg_id and SDN are both primary keys in this table, so I need to insert both. Shg_id has an assigned value already.
My process is this:
DECLARE
l_selected HTMLDB_APPLICATION_GLOBAL.VC_ARR2;
BEGIN
l_selected := HTMLDB_UTIL.STRING_TO_TABLE(:P312_SDN);
FOR i IN 1..l_selected.count
LOOP
INSERT INTO shgm (Shg_id, SDN)
VALUES (:P312_Shg_id, l_selected (i));
END LOOP;
END;
