<script type="text/javascript">
  var box=document.getElementById("box");
  var con1=document.getElementById("con1");
  var con2=document.getElementById("con2");
  var s=document.getElementsByTagName("a");
  var speed=50;
  con2.innerHTML=con1.innerHTML;
  function ScrollUp(){
    if( box.scrollTop>=con1.scrollHeight){
      box.scrollTop=0;
    }else
      box.scrollTop++;
  }
  var i=setInterval("ScrollUp()",speed);
  function Stop(){
    clearInterval(i);
  }
  function Up(){
    i=setInterval("ScrollUp()",speed);
