Showing Custom Fields

In a previous version of Orange CD Andrei showed me how to have custom fields show up in the album view. I used the following commands:

<p><span class="proplabel">On iPod:</span> <span class="propvalue"><b><dax:if(checkbox1)>Yes<dax:el se>No</dax:if></b></span></p>

p><span class="proplabel">Core Collection:</span> <span class="propvalue"><b><dax:if(checkbox2)>Yes<dax:el se>No</dax:if></b></span></p>

These no longer work and I don't know enough to figure out what I should do with the new version.
