Background changes

Ok, so if you check my blog often, you probably noticed that the background keeps changing. It's because I can't find one that I like. Well, actually, when I do a google search, I find several that I like. However, when I try to erase the old HTML code and replace it with a new one, I get an error code. Even though the new background template states it is compatible with "Blogspot". So anyone who is reading this, if you know how to change the background properly, let me know.
