Why Aptana is accusing an error in this code?
<p>I copied <a href="http://unixpapa.com/js/testkey.html" rel="nofollow">this page</a>'s source in Aptana IDE for javascript. But, in the last lines:</p>

<pre><code>                        &lt;script language="JavaScript"&gt;
                            init();
                        &lt;/script&gt;
                    &lt;/body&gt;
                    &lt;/html&gt;
</code></pre>

<p>it is showing at the <code>init()</code> line: <code>syntax error</code>, why? (when run, it works correctly)</p>
