在线客服的函数，在谷歌浏览器里出不来，而在360和IE里都能出来，为什么？很迷茫。。。
我在body里面调用了在线客服的函数，可是在谷歌浏览器里出不来，而在360和IE里都能出来，为什么？
代码是：<script event="onload" for="window" language="javascript"> 
init_Ad_Right();//载入页面后，调用函数init_Ad_Right() 
</script> 
<script language="javascript"> 
<!-- 
function init_Ad_Right() 
{ 
document.all.AdRightLayer.style.posTop = -300; //设置onLoad事件激发以后，广告层相对于固定后的y方向位置 
document.all.AdRightLayer.style.visibility = 'visible'; //设置层为可见 
MoveRightLayer('AdRightLayer'); //调用函数MoveRightLayer() 
} 
function MoveRightLayer(layerName) 
{ 
var x = 20; //浮动广告层固定于浏览器的x方向位置 
var y = 50;//浮动广告层固定于浏览器的y方向位置 
var diff = (document.documentElement.scrollTop + y - document.all.AdRightLayer.style.posTop)*.90; 
var y = document.documentElement.scrollTop + y - diff; 
eval("document.all." + layerName + ".style.posTop = y"); 
eval("document.all." + layerName + ".style.posright = x");//移动广告层 
setTimeout("MoveRightLayer('AdRightLayer');", 0);//设置20毫秒后再调用函数MoveRightLayer() 
} 
//--> 
</script> 
<div id="AdRightLayer" style='position: absolute; width: 119px; height: 200px; z-index: 20; visibility: hidden; right: 12px; top: 600px'>

谷歌浏览器报错是：
