$ is not a function
<pre><code>&lt;script type="text/javascript" src="framework/resources/jquery-1.5.1.js"&gt;&lt;/script&gt;
&lt;script type="text/javascript"&gt;
      var blink = function() {
            $('#blink').toggle();
       };
&lt;/script&gt;
</code></pre>

<p>Throws an error saying </p>

<p>When using an external JavaScript file which gets referred after jQuery I can only seem to use jQuery within the <code>ready</code> function. Is there something I should know about using jQuery in this manner?</p>
