Help with QTY box on product_listings.

[DeltaWolf7]

I have done everything listed in this post > http://oscdox.com/PNphpBB2-viewtopic-t-2426.html but I can't get the QTY box to work.
I have placed the following code in product_listing.php

 case 'PRODUCT_LIST_BUY_NOW':
            $lc_align = 'center';
            $lc_text = tep_draw_input_field($products[$i]['quantity'], '1', 'size="2"') . '<a href="' . tep_href_link(basename($PHP_SELF), tep_get_all_get_params(array('action')) . 'action=buy_now&products_id=' . $listing[$x]['products_id']) . '">' . tep_image_button('button_buy_now.gif', IMAGE_BUTTON_BUY_NOW) . '</a> ';
            break;

And i have also tried placed code in application_top.php for the $quantity with any luck.
Please could someone tell me then best place to put the code?
I am using an unmodified version of OSCMAX 2.0 RC3.

Thank you
