Controlling numbers of products to be displayed

[ueon]

right now my osc page is set to show 10 products per page - i tried adjusting it to 20 in the max values and it's not helping at all

 

I'm looking at the pagination of the "product_listing.php" in the includes/modules - any idea on how to make it display 20 products per page?

 

<?php

  $listing_split = new splitPageResults($listing_sql, MAX_DISPLAY_SEARCH_RESULTS, 'p.products_id'); 

?>

<div class="pagination"><?php

if ( ($listing_split->number_of_rows > 0) && ( (PREV_NEXT_BAR_LOCATION == '1') || (PREV_NEXT_BAR_LOCATION == '3') ) ) {

echo $listing_split->display_links(MAX_DISPLAY_PAGE_LINKS, tep_get_all_get_params(array('page', 'info', 'x', 'y')));

}

?></div>
