Hi michelehahan,
I believe the easiest wasy to accomplish this would be to re-list the item through your eBay account "as is" and then to revise it via the following process to apply your changes after it has been posted:
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) Select All and copy the html in the popup window.
4) Locate the item on eBay and click the "Revise Item" button.
5) Click "Edit Description" then click the "Enter your own html" tab above the description editor.
6) Delete the html that is already there and then paste the copied html in its place and save you changes.
It sounds like you have already completed step 1 above so, instead, you would begin with step 2. I hope this information proves useful
