Hi,

Just forgot to tell you one thing.
Change the following line in code with the page name.

$page_name="yourPage.php";

Sorry, That is one function that I had used to prevent SQL injection.

Please remove that function from the code.
like

$limit=sql_quote($_GET['limit']);

change it to

$limit=$_GET['limit'];

$limit=$_GET['limit'];
//$start=sql_quote($_GET['start']); // To take care global variable if OFF
$start=$_GET['start'];
if(!($start > 0))
{ // This variable is set to zero for the first page
$start = 0;
}

$eu = ($start - 0); 
if(!$limit > 0 )
{ // if limit value is not available then let us use a default value
$limit = 3; // No of records to be shown per page by default.
} 
$this1 = $eu + $limit; 
$back = $eu - $limit; 
$next = $eu + $limit;
