[Plugin: Easy FancyBox] Fancy-Auto not working with inline content

Hey,
I can’t seem to get the fancy-auto pop up to make some inline content show up.
Here is my code;

<a class="fancybox-auto" href="#testboxopen"></a>
<div style="display:none;">
<div id="testboxopen">
<p>It worked</p>
</div>
</div>

It works perfectly when I set the href to an image but now it just doesn’t seem to do anything :S
Thanks
~James
