How do I change details?

[seattlemetaphysicallibrary]

I'm listing a book.  The page count, ISBN, and publication year need to be changed, they are wrong.  But I don't see a way to edit that info.

I started the listing by clicking on a "sell one?" button, which loaded the info for me, but, as I said, I have a different edition, with some changes.  Do I need to delete the listing, and start over from scratch?  Is there a little down arrow or "add" button to click to get access to those three fields?

Thank you

Did you try getting rid of the ISBN number and see if that doesn't let you edit?

I've never used the "sell one like this" method of listing so I'm not sure which options are available.

Normally when you list something and eBay offer to pre-fill the Description etc based on the ISBN you enter there is an option to NOT pre-fill, select/deselect as needed and enter your own information.

This is a frequent problem with Media items because many companies use the same UPC or ISBN for multiple versions/editions of the same item.

There are two ISBN fields, one called ISBN, the ISBN-13,  The numbers on them were reversed.  I deleted the data in the ISBN field, and it does not show on the Preview page, and the ISBN-13 field is not available for modification, at least that I can see.  Which is why I posted the question - how do I find it, to fix it?
