Excluding sideboxes from product list pages

I am trying to figure out how to exclude sideboxes from the product list pages:

http://www.cooltechcentral.com/electronics-112/electronic-dictionaries-299/

I tried adding product_listing, categories_index, and categories_row_index to the tpl_main_page.php file and had no effect. I originally used index but it excluded side boxes on other pages I wanted it on including the home page. At the very least I would like the right sideboxes to show up on the home page.

Try this FAQ which disables the side column on a page-specific basis.

Try this FAQ which disables the side column on a page-specific basis.

I am referencing that FAQ that is why I mentioned both tpl_main_page.php as well as the files I was trying to exclude.

I found this forum topic on Show/Hide sideboxes based on page

http://www.zen-cart.com/forum/showthread.php?t=44364&page=2

NO to exclude the bestseller and specials sidebox from the section in question do I use $cPath?

I am not even sure I am using the right name for the section I am trying to block the sideboxes on. Is it product list category list, Cpath or something else?

I added this to the best_sellers.php from the includes/modules/sideboxes/MY_TEMPLATE/
and at the bottom of the php file right before the last ?>

$show_categories= false;

if (isset($_GET['products_id']) and zen_products_id_valid($_GET['products_id'])) {
if (!($_GET['main_page']==FILENAME_REVIEWS)) $show_review = true;
}
if ($show_review == true) {
$categories_status = " and p2c.categories = > 0 ";}

but the bestseller sidebox still shows up:

http://www.cooltechcentral.com/electronics-112/accessories-1/

What am I doing wrong?

I made a mistake, I want to exclude sideboxes from these types of page as referenced in my original post:

http://www.cooltechcentral.com/electronics-112/electronic-dictionaries-299/

My bad, but the code still does not work.

Anyone have any suggestions?

Is it categories or Product listing? Again the reason I am asking is because I am not sure I am using the terminology right.

Sorry folks, I guess I should have paid more attention to the link canopy sent me because the answer to my problem was there all along.
