$data = mysql_query("SELECT * FROM pubapp WHERE chked=1 and fpub=1 and achked!=1 ORDER BY date DESC") or die(mysql_error());
$total = mysql_num_rows($data);
echo $total;
$LIMIT = 4;
$NEXT=$START+$LIMIT;
$PREV=$START-$LIMIT;

$last = $total;   

$data_S = mysql_query("SELECT * FROM pubapp WHERE $hidn='$dropd' and chked=1 and fpub=1 and achked!=1 ORDER BY date DESC LIMIT $START,$LIMIT") or die(mysql_error());

while($info = mysql_fetch_array( $data_S ))
