Thanks Kevin Really appreciate such a quick reply!
I'm the first to admit I don't know beans about HTML (yay for wysiwyg editors!) so I apologize if I'm missing something obvious.
Homestead has an option to "post an html snippet" and then it prompts me for the html snippet itself, which I C&P'd directly from the appropriate place in the auctiva 'store window' menus on here.
Curiously, I was fiddling with homestead's editor, and they have an advanced thingie wherein the html you put in *that* box shows up automatically between the </head> coding, which I imagine has an intention for navigation menus and such. When I post my Store Window HTML in *that*, it seems to work fine, but is stuck unmovingly at the top of the page mostly under my artistic headers and not in the center where I'd like it.
