สอบถามการสร้างจำนวนรายการใน Paging ทำไมหน้าต่อๆไปไม่มีข้อมูลขึ้นครับ

<?
include("connect.inc");
$strSQL = "SELECT * FROM province";
$objQuery = mssql_query($strSQL) or die ("Error Query [".$strSQL."]");
$Num_Rows = mssql_num_rows($objQuery);
$Per_Page = $_GET["rows"]; // จำนวนข้อมูล / หน้า

$Page = $_GET["Page"];
if(!$_GET["Page"])
{
$Page=1;
}
 
$Prev_Page = $Page-1;
$Next_Page = $Page+1;
 
$Page_Start = (($Per_Page*$Page)-$Per_Page);
if($Num_Rows<=$Per_Page)
{
$Num_Pages =1;
}
else if(@($Num_Rows % $Per_Page)==0)
{
$Num_Pages =@($Num_Rows/$Per_Page) ;
}

else
{
$Num_Pages =($Num_Rows/$Per_Page)+1;
$Num_Pages = (int)$Num_Pages;
}
$Page_End = $Per_Page * $Page;
IF ($Page_End > $Num_Rows)
{
$Page_End = $Num_Rows;
}
?>
