ie error expected identifier string or number

IE 7 was throwing an error while working on some JavaScript
ie error expected identifier string or number
The problem was that I had an extra comma in a hash
this.css({
"position":"fixed",
"top": ( $K(window).height() - this.height() ) / 2 + "px",
"left": ( $K(window).width() - this.width() ) / 2 + "px",
});
It should have been
this.css({
"position":"fixed",
"top": ( $K(window).height() - this.height() ) / 2 + "px",
"left": ( $K(window).width() - this.width() ) / 2 + "px"
});
