Hi Bill,
Since some of your listings failed to post, you should be able to see failure messages within your Auctiva account by clicking the red number in the "Events" section in the upper-right hand corner. There is a good chance you will see an error message there that indicates why the listings were not posted to eBay.
There is also a good chance you will see a non-specific error message there that advises you to contact Auctiva support to see the whole error. If you see this message, please contact our customer support team and we'll be happy to get you the information you need.
You can reach our customer support team by completing the web form on the following page of our site:
