<frameset rows= "40,* " frameborder= "0 " marginwidth= "0 " marginheight= "0 " leftmargin= "0 " topmargin= "0 ">
<frame name= "top " src= "Top.aspx " scrolling= "NO ">
<frameset cols= "220,* " frameborder= "0 " >
<frame name= "detail " src= "Detail.aspx ">
<frame name= "main " src= "MainFrame.aspx ">
</frameset>
</frameset>
