"subcats" = "sub-category" type of category
i.e. a "sub-category" is any category which you set up, which is not a "root" level category. See category management wihin X-Cart admin to understand more... the "Root level" is shown for only the top (1st) level of categories you have added (any categories added below the root level ones are called a sub-category)....

Hope comment helps, cheers, Asiaplay
