[jQuery] Script to keep draggable windows in the main window not working?

[CodingCyborg]

I have a script to keep the draggable windows from leaving the main
window they are in. When I comment out the code everything else works
perfectly. But if I allow this code to be included, not everything
loads, the windows won't move, but nothing shows up in error console.

        jQuery(document).mousemove(function(){
                $('.draggableWindow').each(function(){
                        if(parseInt($(this).css("top")) < 0){
                        $(this).css("top", "0");
                        }
                        if(parseInt($(this).css("left")) < 0){
                        $(this).css("left","0");
                        }
                        newTop= window.height - $(this).outerHeight();
                        newLeft= window.width - $(this).outerWidth();
                        if(parseInt($(this).css("top")) > newTop){
                        $(this).css("top", newTop);
                        }
                        if(parseInt($(this).css("left")) > newLeft){
                        $(this).css("left", newLeft);
                        }
                }
        });

Not sure whats messing it up. I've tried changing a few parts of it to
no prevail. Help is appreciated.
