Use of Checkboxes on reports

Question

Hi
I am using the HTMLDB_ITEM.CHECKBOX function. It works fine in the report, as below;
SELECT
"POOL_CARS"."ID" "ID",
"POOL_CARS"."REG_NUM" "REG_NUM",
"POOL_CARS"."MAKE" "MAKE",
"POOL_CARS"."BHP" "BHP",
"POOL_CARS"."PURCHASE_DATE" "PURCHASE_DATE",
"POOL_CARS"."MODEL" "MODEL",
"POOL_CARS"."COLOUR" "COLOUR",
"POOL_CARS"."STYLE" "STYLE",
"POOL_CARS"."PRICE" "PRICE",
"POOL_CARS"."AVAILABLE" "AVAILABLE",
HTMLDB_ITEM.CHECKBOX(1,"AVAILABLE",
DECODE(AVAILABLE,'Y','CHECKED',null)) "Av ",
"POOL_CARS"."DEPT" "DEPT"
FROM
"#OWNER#"."POOL_CARS" "POOL_CARS"
I want to use the checkbox to cause an update to the table (set Avail to Y where the box is checked, and to N for all other rows). So I have then created a submit button and a process to be run as follows
FOR I in 1.. HTMLDB_APPLICATION.G_F01.COUNT LOOP
UPDATE POOL_CARS
SET available = 'Y'
WHERE ID = to_number(HTMLDB_APPLICATION.G_F01(i));
htp.p('debug' || HTMLDB_APPLICATION.G_F01(i));
END LOOP;
I have a few problems here.
1. When the page is run the check boxes show up fine. When submit is pressed I get
ORA-01722: invalid number.
2. The line 'htp.p('debug' || HTMLDB_APPLICATION.G_F01(i));' does not seem to do anything !
3. I do not understand how to connect the current line within the loop to an actual row as the where clause is not realistic.
Can anyone help.? .

Jelane,
You have to reference the "ID" in your htmldb_item.chekbox api:
htmldb_checkbox(1,"ID",.....
Hope this helps,
