S.O.S.

I'm not smart enough for all this stuff!! I have messed up my blog :) I have been trying for over an hour to get my sidebar back up to where it belongs, but still no success. I've been googling html stuff and it's a bunch of mumbo-jumbo to me...plus every time I think I've got the answer I mess up something else and I have now decided it would be best to just cut myself off :)Does anyone know what I did and how I can fix it???
