I have this working here: http://zcadditions.com/zc10195/index...index&cPath=22

the code provided is not the code from the single_listing_template mod: several things are missing included but not limited to

break;
case 'PRODUCT_LIST_NAME':
$lc_text = TABLE_HEADING_PRODUCTS;
$lc_align = '';
$zc_col_count_description++;
break;
case 'PRODUCT_LIST_PRICE':
$lc_text = TABLE_HEADING_PRICE;
$lc_align = 'right' . (PRODUCTS_LIST_PRICE_WIDTH > 0 ? '" width="' . PRODUCTS_LIST_PRICE_WIDTH : '');
$zc_col_count_description++;
break;
case 'PRODUCT_LIST_IMAGE':
$lc_text = TABLE_HEADING_IMAGE;
$lc_align = 'center';
$zc_col_count_description++;

without drilling into every line of your file, which I do not have the time todo. I suggest you "make note" of your changes and re-upload the original. You shouldn't have to remove any code, simply //commenting it out will work.
