Uncaught ReferenceError: jquery is not defined (anonymous function)
<p>I am trying to learn jquery and seem to be struggling to get it to work how i would expect, can someone please help.</p>

<p>So far I have gone to Jquery and copied and pasted the source code into a .js file which I have named jquery.
I have referenced the file  in the body of my practice page.</p>

<p>I then added</p>

<pre><code>&lt;script&gt;

var lis = jquery('ul li').css('color', 'green');

&lt;/script&gt;
</code></pre>

<p>and in the browser using the developer tools I got the following message
"Uncaught ReferenceError: jquery is not defined(anonymous function) "</p>

<p>I tested jquery by adding</p>

<pre><code>        $('document').ready(function(){
            alert("ready and working!");
        })
</code></pre>

<p>so i am confident that it is working but cant get it to change the css color, which I am trying to do as part of an excercise.</p>
