    var area=document.getElementById(eid);
    var pwindow=window.open("","","scrollbars=1,menubar=1,status=0,resizable=0");
    var pwindow.document.write('<LINK href="finalucg.css" type="text/css" rel="stylesheet">'   );
     //pwindow.document.write("scrollbars=1,menubar=1,status=0,resizable=0");
    pwindow.document.write(area.outerHTML);
