有关上下滚动的图片的问题~~今天从网上找到了这方面的代码~~~放在页面上~~调试可以~~~

我想在同一个页面上用上两次，但一调试就失败，图象不能连续出来卡在那了~~~ 有没有别的方法？
这下面是代码：
<script language="JavaScript1.2">
var scrollerwidth=103
var scrollerheight=106
var scrollerbgcolor='white'
//3000 miliseconds=3 seconds
var pausebetweenimages=3000
var slideimages=new Array()
slideimages[0]='<a href="http://www.cnn.com"><img src="image/tn05061.jpg" border="0"></a>'
slideimages[1]='<img src="image/tn05062.jpg">'
slideimages[2]='<img src="image/tn05061.jpg">'
slideimages[3]='<img src="image/tn05062.jpg">'
slideimages[4]='<img src="image/tn05061.jpg">'

else

function move1(whichlayer){
tlayer=eval(whichlayer)
if (tlayer.top>0&&tlayer.top<=5){
tlayer.top=0
setTimeout("move1(tlayer)",pausebetweenimages)
setTimeout("move2(document.main.document.second)",pausebetweenimages)
return
}
if (tlayer.top>=tlayer.document.height*-1){
tlayer.top-=5
setTimeout("move1(tlayer)",100)
}
else{
tlayer.top=scrollerheight
tlayer.document.write(slideimages[i])
tlayer.document.close()
if (i==slideimages.length-1)

else
i++
}
}
