I originally uploaded this page provided in the mod:
/catalog/admin/includes/languages/english/products_attributes.php
It had made the revisions to the code at the beginning of the page. However, when I moved this code to the bottom of the page, per the instructions, it fixed everything:
/* BOF Linkmatics attributes sets */
define('TABLE_HEADING_OPT_SORT_ORDER', 'Sort Order');
/* EOF Linkmatics attributes sets */
Add this line (before the '>?' at the end of the file)
...(or replace existing file with included file):<-THIS DID NOT WORK!!
