Javascript-форум - Не работает OnMouseMove

Есть вот такой код:

var left=100,top=100;
var x, y,x1;
var jseyeimg="jseyeblue.gif";
var jseyesimg="jseyes.png";
var jseyeso=null, jseye1=null, jseye2=null;
browsername = navigator.appName;
if(browsername.indexOf("Netscape")!= -1)
{
  browsername="NS";
 
}
else
{
  if(browsername.indexOf("Microsoft")!=-1)
  {
    browsername="MSIE";
    
  }
}

  function eyemove(x2,y2,a,b){
  var tanteeta,opp,adj;
  var fx,fy;
    if (jseyeso && jseye1 && jseye2 && jseyeso.style) {
      if((x2 > a) && (y2> b))
      {
       tanteeta=Math.atan((y2-b)/(x2-a));
       opp=Math.round(Math.sin(tanteeta)*35*10000)/10000;
       adj=Math.round(Math.cos(tanteeta)*35*10000)/10000;
       fx=a+adj;

       if((x2<fx) && (y2<fy))
       {

       }
    }

Работает в IE и Maxthon. Не работает в Mozilla, Opera, Chrome.
Помогите с решением. Никак не могу понять почему!!
Умоляю, заставьте его работать в вышеуказанных браузерах!!! :cray: :cray: :cray: :cray:
