dynamic sidebar footer widget issue

the styles are not getting applied, becuase there is a missing closing curly bracket } in this section:

#slide_background {
    width: 780px;
    height: 480px;
    position: relative;
    margin: 0 0 0 97.5px;

Anyone know how to create a footer widget area? I have a custom theme with sidebar widget area but I want a footer one. I follow an instruction I found here and it disabled my entire theme.
Does anyone have this ability that I can hire to do this?
