Bren treasures....IF you are revising in ebay and relist later through your saved listing page, you will need to change in auctiva also.
NOW...if you do from closed page, not sure how that works, but would guess they will transfer over in new category.
Most people I know relist through closed...I do from saved listing page...so IF I make a change on the bay I make on saved too. Though normally, I just make changes when listing ends and do it in saved page as they end.
Hope this makes sense.
