Javascript-форум - Анимация глаз на Javascript

Всем привет! Мне жужно на Javascript написать программу, которая бы анимировала покадрово движение глаза. Программу я написал, но она почему то не работает. Если есть ошибки подскажите буду благодарен!

Вот текст программы:

function eyesmove(x,y)

var ex, ey, dx, dy;
if(leftEye && rightEye)

var eyel=getEyeballPosition(dx,dy);
leftEye.src='Position/Left'+eye1+'.png';
ex+=56; dx-=56;
var eye2=getEyeballPosition(dx,dy);
rightEye.src='Position/Right/'+eye2+'.png';

}

function getEyeballPosition(xm,ym)
{
var r, xr, yr;
r=Math.sqrt(xm*xm+ym*ym);
xr=x/r; yr=y/r;
if(r<=20)return "pupilcenter";
