using no conflict with jquery
<p>I need to use noconflict in my web site,but i think there is a problem.Here is my code :</p>

<pre><code>calling... src="jquery-1.7.2.min.js" 
var jQuery_1_7_2 = jQuery.noConflict(true);

(function($){
    $(window).load(function () {
        $("#content_1").mCustomScrollbar({
            advanced:{
                updateOnContentResize: true
            },
            scrollButtons: {
                enable: true
            }                                          
        });
    });
})(jQuery_1_7_2);
</code></pre>
