Hi 3WGifts,
In order to use Auctiva's templates in your eBay listings, you must create your listings through Auctiva using our lister form that can be reached via the "New Listing" link within your Auctiva account.
About half way through our lister page, you will find a big, blue "Select Template" button, which you can click to browse our complete template library and select one to use with your listing.
I hope this information proves useful. If you have any further questions or concerns, please file a support request using the appropriate link on our help page:
