No worries. I'll be happy to help you. I am online all day today. So if you post, I'll see it
You need to configure an eBay store Auction profile. Just like the eBay Profile.
Go to the Aucction Wizard menu. Along the top, go to
File | Auction profile
In the "Auction Site" field, select "Ebay stores.
Then complete all the fields just like you did for your eBay profile. But you want to be sure to include the correct user id, not the store name. Your store name could be ratty rags and your user id is Nice Towels. The User id field should be "Nice Towels' not the Store name of "Ratty rags"
Does that help?
