Can't find the mistake, error shown unexpected token ILLEGAL
<p>Can't find the mistake, i just want to change the visibility with the <code>click</code></p>

<pre><code>&lt;script type="text/javascript"&gt;
$(#register_link).click(function(){
     $(#signin).animate({visibility:hidden;},"slow");
});
&lt;/script&gt;
</code></pre>
