table name - news

I create pagination code

here I am passing city and state from Navigation bar.
And on basis of that i Tried to show Row with pagination pages.

It works but on 2,3,4,5...N pages it shows error.

Simply Pagination Not fetching data with where condition.
plz suggest proper solution.


when page loads it gets url like
http://localhost/bhaskarhindi/city.php?state=19&city=16
and display pagination rows below.

But when i click on page2 it show url like
http://localhost/bhaskarhindi/city.php?page=2
and shows
error
Undefined index: city
Undefined index: state

<?php
require_once('includes/config.php');
$Admin = new admins;
$baseString = "detail.php";
$cit = $_REQUEST['city'];
$sta = $_REQUEST['state'];
?>

<?php
$page = (int) (!isset($_GET["page"]) ? 1 : $_GET["page"]);
$limit = 1;
$startpoint = ($page * $limit) - $limit;
$statement = "news where state_id = '$sta' and city_id = '$cit'";
?>
<?php
mysql_set_charset('utf8');
$sql="select id,story,headline,photo from {$statement} order by id desc LIMIT {$startpoint} , {$limit}";
$query=mysql_query($sql);
?>
