  </style>

  <script language="JavaScript" type="text/JavaScript">

  <!--

  window.onerror = function(){return true}

  function MM_openBrWindow(theURL,winName,features) { //v2.0

  window.open(theURL,winName,features);

  }

  //-->

  </script>

  <table width=500 border=0 align=center cellPadding=0 cellSpacing=0  background="http://s16.sinaimg.cn/middle/60d27f6dt7942731cd87f&690">

  var n=0;

  var showNum = document.getElementByIdx_x("num");

  function Mea(value){

  n=value;

  setBg(value);

  plays(value);

  }

  function setBg(value){

  for(var i=0;i<4;i++)

  if(value==i){

  showNum.getElementsByTagName_r("td")[i].className='woon';

  }

  else{

  showNum.getElementsByTagName_r("td")[i].className='wooff';

  }

  }

  function plays(value){

  with (fc){

  filters[0].Apply();

  for(i=0;i<4;i++)i==value?children[i].style.display="block":children[i].style.display="none";

  filters[0].play();

  }

  }

  function clearAuto(){clearInterval(autoStart)}

  function setAuto(){autoStart=setInterval("auto(n)", 5000)}

  function auto(){

  n++;

  if(n>3)n=0;

  Mea(n);

  }

  function sub(){

  n--;
