Hi beautifulstuff,
The "Create Similar" option is only available on your saved listings page because that is where listings are stored in the lister page format, from which they can be posted to eBay.
It would be problematic to have these options available on the active or closed listings page because an active or closed listing doesn't necessarily have a saved listing associated with it. For example, if an active listing was posted through eBay, there would be no saved listing in your Auctiva account from which to create similar, therefore, this option would be misleading and would not function.
Most revisions can be done easily through eBay’s “Revise Your Item” form by choosing to edit the appropriate section of the listing. If you would like to edit part of the description, be sure to click “Edit Description” followed by the “Standard” tab on the editor to exit html mode.
The revisions that cannot be done directly through eBay’s “Revise your Item” form are changing templates and rearranging/adding/removing images within a template. To make these types of revisions, please proceed with the following steps:
1) Locate your listing in your Saved Listings folder, make any necessary changes, and save.
2) Check the box next to your updated listing in your Saved Listings folder and click the “Get html” button.
3) Copy the html in the popup box.
4) Locate the item on eBay and click the "Revise Item" button.
5) Click "Edit Description" then click the "Enter your own html" tab.
6) Paste the copied html in place of what's there and save your changes.
To add an image to an active listing, you can use the "Add Images" button on the "Active Listings" page.
Check the box next to the listing you want to add images to, select the images in the pop up box and click "Add".
To replace an image in an active listing, go to Auctiva -> Images(tab) -> Manage Images, check the box next to the image you’d like to replace, then click the “Replace” button.
