HTML rescue, please!

I know a little bit about HTML. I can usually get into the code and make some minor changes on my blog. But I can't write code and I can't make major fixes. Which leaves me right now in a bit of a pickle because it seems that the entire right side of my blog is messed up, as in gone and doesn't exist.

I've been contemplating a blog re-design, but I wasn't quite ready for it right now. Though it kind of looks like that decision might have been made for me.

Ugh!
