How to set up multiple sliders with flexslider?

Question

I use flexslider, when i follow instructions on their website it doesn't work for multiple sliders, this is the code:

i need a controler nav on both sliders, instructions are here: http://www.woothemes.com/flexslider/

Does anyone what i'm doing wrong?

<script src="http://code.jquery.com/jquery-1.6.4.min.js"></script>
<link rel="stylesheet" href="http://www.esens.nl/assets/templates/esens/flexslider/flexslider.css" type="text/css" media="screen" />
<script src="http://www.esens.nl/assets/templates/esens/flexslider/jquery.flexslider-min.js"></script>

<!-- Target sliders individually with different properties -->
<script type="text/javascript" charset="utf-8">
  $(window).load(function() {
    $('#main-slider').flexslider({
      animation: 'slide',
      controlsContainer: '.flex-container'
    });

    $('#secondary-slider').flexslider();
  });
</script>



<!-- Somewhere in the  of your page -->
<div id="main-slider" class="flexslider">
  <ul class="slides">
