Problems with the changing of the Layout

Sigh. I suck at things pertaining to the web or just computers in general so, well I've been trying to upload a skin from blogskins.com and well, its driving me nuts because they just don't seem to work! Since I'm such a dummy, I have no idea what I'm doing. I am so out of my league.

Anyway, about other things, tomorrow, I have some sort of thing I have to go to. Its for a pretty decent after school activity. Hope I make the cut. That's the reason I'm a bundle of nerves.
