Integration of two different jQueries
<p>In my code listed below, jQuery is version 1.9.1 and jQuery1 is version 1.2.6, how will I be able to integrate both of them so that both will be compatible with each other?</p>

        &lt;title&gt;Auto Complete Input box&lt;/title&gt;
        &lt;link rel="stylesheet" type="text/css" href="jquery.autocomplete.css" /&gt;
        &lt;script type="text/javascript" src="js/jquery1.js"&gt;&lt;/script&gt;
        &lt;script type="text/javascript" src="js/jquery.js"&gt;&lt;/script&gt;
        &lt;script type="text/javascript" src="js/jquery.autocomplete.js"&gt;&lt;/script&gt;
        &lt;script&gt;
            $(document).ready(function() {
                $("#tag").autocomplete("autoCompleteMain.php", {
                    selectFirst: true
                });
            });
        &lt;/script&gt;
    &lt;/head&gt;
    &lt;body&gt;
        &lt;form&gt;
            &lt;label&gt;Tag:&lt;/label&gt;
            &lt;input name="tag" type="text" id="tag" size="20" /&gt;
        &lt;/form&gt;
    &lt;/body&gt;
&lt;/html&gt;
</code></pre>
