BDP RSS Help

I have set up a feed using the BDP RSS but nothing is showing on my website. Here is the code I added to my sidebar:

<div class="strawbale"><h2>strawbale updates</h2>
<ul><?php BDPRSS2::output(1); ?>
</ul>
<img src="http://www.varresa.org/profile.jpg">

The website is http://varresa.org

Thanks for the help!
