I need lots of help!, I pretty much suck at html Options

[Hoodster777]

Hey! I made a layout for my site, http://www.xanga.com/home.aspx?user=Whatsername87, and now I'm having lots of problems with it. I can't change the color of the text, underneath the banner I had put a link to my layout site and now next to it, it says "text-align: center", which was part of the html that I used, with my subscriptions; I had the code in to put their real names in and now it stopped working, and I can't change the title of my site, here's what I put in my header box:

<!-- begin code provided by createblog.com --><br /><br /><script type='text/javascript'><br />document.title = (<S> Sadie G. </S> Shannon H. she's crazy, see?);<br /></script><br /><!-- end code provided by createblog.com -->

So if anyone could help me with this I'd really appreciate it!

Edit- I forgot to say, if this makes a difference, I use Firefox as my browser.
