I added a column to the listings table using phpMyAdmin called Category_Type (listings, services, jobs, etc.)

My issue is I've been trying to call on that value when I edit or add a listing. What I am attempting to do is for the purposes of a business with more than one location. I have everything else in place except for the edit location and add location. both of which will start the process from the my listings screen with an edit listing and add location link.

My question is...between the template>tpl>controllers>add_listing>step_form.tpl , template>tpl>controllers>edit_listing>step_form.tp l, includes>classes>rlListings.class.php files...how do I call on myDB_listings_Category_Type (which is the column I added in the db)
