Bootstrap carousel not sliding

Did you include this script:

<script language="JavaScript" type="text/javascript">
  $(document).ready(function(){
    $('.carousel').carousel({
      interval: 2000
    })
  });    
</script>

And even it its not working, please check whether you are calling the above script before calling the jquery. So, it should be like this:

<!-- Calling jquery first -->
<script language="JavaScript" type="text/javascript" src="scripts/jquery.js"></script>
<script language="JavaScript" type="text/javascript" src="scripts/bootstrap.min.js"></script>
  <!-- Carousel -->
<script language="JavaScript" type="text/javascript">
  $(document).ready(function(){
    $('.carousel').carousel({
      interval: 3000
    })
  });    
</script>
