jQuery calendar, doesn't work properly
<p>I try to implement jQuery calender at my homepage: This is the way I do it:</p>

<pre><code>&lt;!DOCTYPE html&gt;
&lt;html lang="en"&gt;
&lt;head&gt;
&lt;meta charset="utf-8"&gt;
&lt;title&gt;jQuery UI Datepicker - Default functionality&lt;/title&gt;
&lt;script src="jquery-1.7.1.js"&gt;&lt;/script&gt;
&lt;script src="jquery.ui.core"&gt;&lt;/script&gt;
&lt;script src="jquery.ui.widget.js"&gt;&lt;/script&gt;
&lt;script src="jquery.ui.datepicker.js"&gt;&lt;/script&gt;
&lt;script src="core.js"&gt;&lt;/script&gt;
&lt;script&gt;

$(function() {
    $( "#datepicker" ).datepicker();
});
&lt;/script&gt;
&lt;/head&gt;
&lt;body&gt;

&lt;div class="demo"&gt;

&lt;p&gt;Date: &lt;input type="text" id="datepicker"&gt;&lt;/p&gt;

&lt;/div&gt;


&lt;/body&gt;
&lt;/html&gt;
</code></pre>

<p>In the same folder I have all the javascripts that are required. But when I try to click inside the form, no calendar is showing. Why? Thanks!</p>
