Mary,
Sounds like you edited your item on Auctiva? If so, you'll then need to manually revise your item on eBay. One thing that may help is our Get HTML feature. From the saved listings page, check your listing you want and hit the button for Get HTML. Then copy and paste that text and revise your item directly on Ebay, choose the edit description option and replace what is currently there with what you copied.
Hope that makes sense. If not, contact our support guys here and they can help you more.
