Thanks, but I meant something more readable. So far, I have this but this is not working:

   function PositionTop()
   {
      lnOffset=0
      loWindow=window.parent.oParent
      if (typeof loWindow.pageYOffset != 'undefined')
      {
         lnOffset=loWindow.document.documentElement.scrollTop
      }
      else
      {
         lnOffset=loWindow.document.body.scrollTop
      }
   }
