Dynamic countdown to redirect not working

[Faks]

code is taken from phpacademy video jQuery Tutorials: Dynamic countdown to redirect

<script type="text/javascript">

        $(document).ready(function() {

                var    number = 10;

                var url = 'http://faks.sytes.net';

 

                function countdown() {

                        setTimeout(countdown, 1000);

                        $('#box').html("Session Edning In" + numbers + "seconds.");

                        number --;

 

                        if(number<0) {

                                window.location = url;

                                number = 0;

                        }

                }

 

                countdown();

               

        });

 

</script>

<div id='box'></div>

 

Problem is simple countdown doesn't appears maybe somebody knows how to fix it ?

any way here is a demo page code in live action http://hostings.flush.ws/tests.php | status: broken

This line $('#box').html("Session Edning In" + number + "seconds.");

 

Take the s off of numbers
