That appears to be one of the stock Auctiva templates, the Curly Black on Black. If you use the "Customize an Auctiva Template" on the LISTINGS tab page, that will take you to the template editor, where you can modify (or copy) the template code to your own HTML editor for changes.
I copied the code to the practicewriter site, so you can get best assistance with changes from the Forum.

I also see a possible bug in the template. Color #666 isn't beginning applied to the Description header.
Looks like a bug with the whole Curly group. I can fix it, but that's dependent on any changes you might want.Neil (or someone at Auctiva), didn't this Curly group have a code bug reported previously? I see where the Style sheets are getting more complex, so I'm guessing it's an update error.

Edit: I took a stab at fixing the template. It was missing a normal TABLE and a DIV that operates with that code section. Neil or someone can check my work.
Here's the update on a new practicewriter link.http://practicewriter.com/vu/?55FAB
