My problem is that when i run this code in my computer, i wall fail becouse of the hyperlink of the pagination not function when i click it. But when i run in other people computer, It was no problem at all. I wonder to know what happen to my coding . Is it different version of php also reflect the output?

<?

$result = mysql_query($query);

$page_name="list.php";

$display =5;
$XX = 'Sorry, no results were found!';
// If there are no records then startrow
//     is 0
if (empty($startrow)) {
   $startrow=0;
}

$query2 = "SELECT ID,Name FROM listofitem  LIMIT $startrow, $display";

$result2 = mysql_query($query2);

echo "<table border='1'align=center>

$counter = 0;
