function getLeftPostion( theObj )
{
    var pos = 0;
    while ( theObj != null )

    //get the Object which contain theObj.
    theObj = theObj.offsetParent;
    }
    return pos;
}
function getTopPostion( theObj )
{
    var pos = 0;
    while ( theObj != null )

{
    var isBadVersion=true;
    var curVer=navigator.appVersion;
    var pos=parseInt(curVer.indexOf("MSIE"));
    if (pos>=1)

    }
    if (isBadVersion)
    {
    var msg="This page may not be displayed properly: "+
       " This product requires Microsoft Internet Explorer 5 or later browser only.";
    alert(msg);
    }
}
//check the browser version
checkVersion();
// the array of comboBoies
theArray = new Array();
function combobox(objId, objHandler)
{
