Hi Cathy,
Thanks for letting us know about this. Based on the error message you are receiving, it sounds like your listings are missing one or more pieces of information that are required to post them. If you open up the Saved Listing of one of those items and click the "Post" button at the bottom of the page, a red box should appear at the top of the page letting you know what is wrong is the item cannot be posted.
It is likely that the same issue is affecting all of your listings so, once you figure out what needs to be corrected with respect to one listing, you will probably find that the same change needs to be made to the rest of your listings that cannot be posted.
If you are still unable to figure out why these listings cannot be posted, I recommend contacting our customer support team using the web form on the following page:
