Oops! Sorry for the large number of ads on here. Long story short I goofed the setup. I knew they wouldn't show up for me, due to Adblock Plus. (One of my most favoritest Firefox plugins EVAR!) What I didn't realize is that it would also block their representation on the Blogger layout design screen! So I had a bunch, at the top, when I thought I had none, and intended to just put one at the bottom. Mega chalupa!
