I need to define the category in the conformation e-mail because my site www.nflfeatherflags.com has products with the same name and price. Any ideas?

The site has been selling and I really need to fix it asap. so far the only thing I could find is the

/includes/languages/english/checkout_process.php

and it looks like it defines what goes in the e-mail but I don't know what terms it will understand?

if i copy the line
define('EMAIL_TEXT_PRODUCTS', 'Products');

and make a new one that looks like
define('EMAIL_TEXT_CATEGORY', 'category');

will that make the category show up or will it just mess things up? I don't even know how to test it grrr someone PLZ HELP!!
