if (isset($_POST["search"])){
$result=mysql_query("select count(*) from reg_phone");
$row=mysql_fetch_row($result);
$tr=$row[0];
$rpp=4;
$pn=1;
if(isset($_GET['pn']))
{
$pn=$_GET['pn'];
}
$tp=($tr/$rpp);
if($tr/$rpp>=0)
{
$tp++;
}
$from=(($pn-1)*$rpp)+1;
$to=($pn)*($rpp);
$show = "SELECT * FROM reg_phone where Id between $from and $to";
$rs = mysql_query($show) or die(mysql_error());
#****results in Grid****
