Okay, So I am trying to add related products to my product page, and am following this tutorial: http://wp-types.com/learn/create-an-ecommerce-wordpress-site/related-products-widget/, but upon step 1a, part 5; I do not have an option for "product categories" on my dropdown. Here is a screenshot of my options: http://dancevideosdirect.com/images/screenshot.jpg. What am I missing here?
Thanks
