Sideskift

Kode 

<form action="artikler.php" method="post"> <hr>
<select name="show"> 
<? 
include("tilslut.php"); 
$i = 0; 
$sql = "SELECT id FROM salg_artikler"; 
$query = mysql_query($sql); 
$num = mysql_num_rows($query); 
$average = $num/10; 
$pages = ceil($average); 
$page_number = 0; 
while ($page_number < $pages) 
{ 
$test = $pages-1; 
$page_number++; 
$show_number = $page_number*10-10; 
echo("<option value=\\"".$show_number."\\">".$page_number."</option>"); 
} 

?> 
</select> 
<input type="submit" value="Vælg"> 
<? 
if (!$show) 
{ 
$show = 0; 
} 
?>
<?
$query = mysql_query("SELECT * FROM xxx ORDER BY id DESC LIMIT $show, 10") or die(mysql_error());  
while ($row = mysql_fetch_assoc($query)) {
?>

Kode 

<?
if(empty($HTTP_GET_VARS) || isset($_GET))
{
  $HTTP_GET_VARS = $_GET;
}
if(isset($HTTP_GET_VARS)) {
  foreach($HTTP_GET_VARS as $key => $val) {
    if(!isset(${$key})) ${$key} = $val;
  }
}
?>

Jeg er stødt på et lille problem. Jeg vil lave en sideskift-dropdown, men det går ikke lige så godt.

Jeg har lavet denne kode:

Kode 

<form action="artikler.php" method="post"> <hr>
<select name="show"> 
<? 
include("tilslut.php"); 
$i = 0; 
$sql = "SELECT id FROM salg_artikler"; 
$query = mysql_query($sql); 
$num = mysql_num_rows($query); 
$average = $num/10; 
$pages = ceil($average); 
$page_number = 0; 
while ($page_number < $pages) 
{ 
$test = $pages-1; 
$page_number++; 
$show_number = $page_number*10-10; 
echo("<option value=\\"".$show_number."\\">".$page_number."</option>"); 
} 

?> 
</select> 
<input type="submit" value="Vælg"> 
<? 
if (!$show) 
{ 
$show = 0; 
} 
?>
<?
$query = mysql_query("SELECT * FROM xxx ORDER BY id DESC LIMIT $show, 10") or die(mysql_error());  
while ($row = mysql_fetch_assoc($query)) {
?>

Forstår seriøst ikke hvorfor det ikke virker, ...

Får du nogen fejlmeddelse?
