Blogger problems

As you may notice the blog headers for some reason are screwed up. I keep getting this 'undefined undefined' garbage at the top, the titles aren't in bold, and since Blogger's upgraded their template editors, and I can't tell HTML from a car crash, I have no idea exactly what to tweak to correct this. I'm going to keep working at it, and I'll try to get it fixed ASAP. Until such time as I do, please bear with me and don't think I'm a twit.
