Adding a custom aside to Sidebar

[howardm]

Hi,

I have this Web site:  http://chestradiologists.org

I'm trying to add this to the Sidebar (as RadChest.html):

......

<section>

  <h1>Links</h1>

  <ul>

      <li><a href=“http://radchest.macminicolo.net”>Collaborative Teaching File</a></li>

        <li><a href=“http://www.osirix-viewer.com”>OsiriX</a></li>

  </ul>

</section>

....

I now have this in _config.yml :

default_asides: [custom/asides/RadChest.html, asides/recent_posts.html, asides/category_list.html, asides/github.html, asides/delicious.html, asides/pinboard.html, asides/googleplus.html]

.......

Now the Sidebar is as shown in the attached image.

Why is this the case ?

What am I doing wrong ?

Thanks,

Howard
