It's difficult from here to walk you through it but you have to first make sure you have a shipping preference set up to choose from and let it be your default preference.Next, just make sure you choose the right category, and fill in a price and all the other options available. You also have to make sure you have a quantity entered, which allows the item to be visible. Do you have all these things set up? Last, make sure your account is set up to be active and is not in stealth-mode. That a setting in your profile.
