<b:if cond='data:blog.pageType != "item"'>
<div expr:id='"summary" + data:post.id'><data:post.body/></div>
<script type='text/javascript'>createSummaryAndThumb("summary<data:post.id/>");</script>
<span class='rmlink' style='float:left'><a expr:href='data:post.url'>READ MORE - <data:post.title/></a></span>
</b:if>
<b:if cond='data:blog.pageType == &quot;item&quot;'><data:post.body/></b:if>
