<frameset rows="*,50">
          <frame src="a.php" NORESIZE frameBorder="no" framespacing="0" border=0 marginwidth="0">

          <frame scrolling=no src="b.php" NORESIZE frameBorder="no"  framespacing="0" border=0 marginwidth="0">

    <frame src=drag.php scrolling=no NORESIZE id="frame_drag"  frameBorder="no"  framespacing="0" border=0 marginwidth="0">
    <frame src="c.php?count=<?php echo $count;?>" frameBorder="no"  framespacing="0" border=0 marginwidth="0">
