Layouts not working, Some help please? Options

[xFadingDreamsx]

Well I saw a layout that I wanted to use today and I copied the code from here and then it jsut messed up all the other codes I had in there when I hit preview. Not only that but they layout didn't shop up at all. So I thought it was just the layout so I went to try another and the same thing happened. So I had to clear out everything in the 'about me' section. Does anyone know went wrong or is having the same problem as I am?

Never mind sorry for wasting your time.
