Thank you for your timely response!  Much appreciated.  🙂

THE most important step in posting your finished ad is one eBay (in their wisdom LOL) don't advise you of.  You have to request a 4-digt code by SMS and enter it to "authorise" your ad before you can post  it.

I must say that eBay manages to post the most unhelpful help [sic] I've ever seen.
