how to format post in entry summary

See http://drivingnews.us/rcp for the blog. I am attempting to use a ‘formatted’ post for each blog entry. For most displays, its just fine, but when I click on categories, the html is removed from the formatted part.

The formatted post html is:

<link href="http://drivingnews.us/rcp/rcpstyle.css" rel="stylesheet" type="text/css" />
<div id="rcp">
<dl>
<dt>RCP #</dt> <dd id="post">1</dd>
<dt>Reason</dt> <dd id="post">Remove typo</dd>
<dt>Date Received</dt> <dd id="post">23Feb10</dd>
<dt>Proponent</dt> <dd id="post">Jeff Morse</dd>
<dt>Status</dt> <dd id="post">Recommended</dd> </dl>
  ... detail here
</div>

With a selected category (there is only one ‘General Rules’), the html looks like:

<div class="entry-summary">
<p>RCP # 1 Reason Remove typo Date Received 23Feb10 Proponent Jeff Morse Status Recommended CHAPTER 3INTRODUCTION AND DEFINITIONS All drivers at ADS-recognized competitions must be current A</p>

How do I retain the full post (or a proper subset of it) even in the summary?

Any help would be appreciated,
Mike Arnold.
