Hi all, is this all fine now or am I duplicating some scripts? Thank you!

PHP Code:
<script type="text/javascript" src="/js/jquery.min.js"></script>
<script type="text/javascript" src="/themes/development-bundle/ui/jquery.ui.core.js"></script>
<script type="text/javascript" src="/themes/development-bundle/ui/jquery.ui.position.js"></script>
<script type="text/javascript" src="/themes/development-bundle/ui/jquery.ui.widget.js"></script>
<script type="text/javascript" src="/themes/development-bundle/ui/jquery.ui.dialog.js"></script>
<script type="text/javascript" charset="ISO-8859-1" src="/js/fns_index.js"></script>
<script language='javascript'> 
$(document).ready(function(){
    $('#debug').ajaxStart(start_window);
  $('#debug').ajaxComplete(stop_window);  
});
</script>
