Hi nettiefreynolds,
Welcome to the community forum and thanks for posting.
If your email address has already been set up on your account and you have received payments to it, that means there are no issues on our end. It is very strange that you are getting that error when trying to sell something on eBay. I recommend initially reaching out to eBay to see if there is something wrong on their side. If not, you can find our customer support details by clicking 'Help & Contact' at the bottom of any PayPal page. You can also reach out to us on Facebook www.Facebook.com/PayPalUK or on Twitter @AskPayPal . Our teams there will be happy to help.
