Hi sellitonline - Yes, you can change your template. Making such changes in an active listing is pretty easy. If you wish to make changes within the template area (description, seller details, pictures, OR THE TEMPLATE ITSELF), you can copy and paste the HTML from your revised listing in Auctiva to your active listing in eBay as follows:
1) Locate your listing in your Saved Listings folder in Auctiva, open it, make any necessary changes, preview, and save.
2) In your Saved Listings folder, click the <HTML> icon to the right of your listing.
3) Select all of the HTML in the popup box and copy it.
4) Locate the item on eBay and click the "Revise your item" link.
5) Click the "HTML" tab on top of the Description box.
6) Select all of the HTML that's there, paste the copied HTML in its place, and save your changes.
Hope this helps.
