지금은 10개씩 뽑고 있는데요 한페이지당..

이걸 5개씩 뽑으려면 어디를 어떻게 바꿔줘야 하나요?

--------소스---------

$list_num  = 10;
  
$but_num   = 5;
  
if(!$pg_start)     $pg_start=0;
  
if(!$p)            $p=1;

$query_1 = "select  * from estimate_list   order by no desc limit $pg_start , $list_num";
$query_2 = "select  * from estimate_list   order by no desc";

$result=mysql_query($query_1, $dbconn);
$result_2=mysql_query($query_2, $dbconn);
$rows_2=mysql_num_rows($result_2);


$rows=mysql_num_rows($result);
$fields=mysql_num_fields($result);
$total_num=$rows_2;


              

if($rows)
{  
  while($row=mysql_fetch_row($result))
        {
                $no=$no+1;
        $no_1=$rows_2 -(($p-1)*$list_num + $no )+1;
        
                echo("

          <td height=25 align=center>$row[1]</td>
        
          <td height=25 align=center>$row[12]</td>
          <td height=25 align=center>$row[15]-$row[16]-$row[17]</td>
