Default dynamic sidebar code invalidating my page

Hi,
I recently added a dynamic sidebar to my company’s website (centurionsystems.com) in order to put the qtranslate widget I’m using in the sidebar and not in the footer where it was being lost. I added a text widget as well to make it even clearer what the widget does. However, adding this makes my code invalid. I get these errors:
…" class="widget-container widget_text"><h3 class="widget-title">Change Languag… Element li not allowed as child of element div in this context. (Suppressing further errors from this subtree.)

So it’s having difficulty with this:

<li id="text-3" class="widget-container widget_text"><h3 class="widget-title">Change Language</h3>
<div class="textwidget"><p>To View this site in another language, please use the drop down menu below.</p>
  199</div>

But since I’m only using this in my code:

<?php if ( ! dynamic_sidebar( 'secondary-widget-area' ) ) : ?>
		<?php endif; // end primary widget area ?>
		</div><!-- #secondary .widget-area -->

I honestly don’t know how to fix this issue.
Any help is greatly appreciated.
