Multi-row delete

Question

Hello,
I want to display a checkbox in a multi-row query for deletion.
when the user will submit, I want to delete all checked record.
I've tried to do it by creating a checkbox in the select statement of the query (select HTMLDB_ITEM.CHECKBOX (1, 'Y') checkbox, ...) and create a process to do the delete. Here my process code:
declare
l_val_rows varchar2(400) default null;
begin
for i in 1..htmldb_application.g_f01.count loop
if instr(nvl(htmldb_application.g_f01(i),0),1) > 0 then
delete gsr_corporates where id = htmldb_application.g_f02(i);
end if;
end loop;
end;
2 problems:
1)
When I submit, if my checkbox is not checked, I get error "Error in mru internal routine: ORA-20001: no data found in tabular form". If checked, it is working.
2)
When checked, I get the error "Error in mru internal routine: ORA-20001: Checksum column ("FCS") is required and was not supplied".
So, is it a good way to do what I want? If yes, what's wrong? If no, what is your suggestion?
Thank you
Jean

Jean,
Please take a look at this example:

The problem is that when a checkbox is not checked, there is no corresponding entry in the array. Thus, the array indexes for f01 and f02 will be out of sync. To fix this, make the value of a checkbox, when checked, the primary key of the row you want deleted. Then you can simply walk through one array and delete every row that corresponds to an entry in it.
