When using Trade Runner to create a listing on Trade Me is it essential to map the product you want to list to a category on Trade Me.  If you do not map a product in Trade Runner to a Trade Me Category the product will not list.

Map a product to a Trade Me category

From the Dashboard, you will see the Products section, underneath the summary of total products you can see 'Not Listed'. 

Under products that 'Need a category to list in' - click 'Fix Now'.  This will take you to the Manage Listing - Needs category to list screens.

You can map Category to Category or Product to Category. Category to Category is your Retailer Category to the Marketplace Category.
