Hi doggythis,
Since this error message is being returned in response to your listings, eBay has most likely placed a restriction on your account, or a selling limit on how many of those particular items can be listed on eBay at one time. For further assistance with this matter, please file a support case using the appropriate link on our help page:

Our support staff will be able to look up the exact reason why eBay rejected these listings.
