element values don't display with value-of

I'm having a problem getting element values to display. 
Here is the XML structure:

articles
	article
		name /name
		description /description
		bodyblock 
			summary /summary
			analysis /analysis
			sources
			     source /source
			     source /source
			     source /source
			/sources
		/bodyblock
	/article
/articles

When a bodyblock node is the current context, I call the 
following template to show the sources:

<xsl:template name="list-sources">
<xsl:for-each select="sources/source">
	<xsl:value-of select="source" />  (value here) 
<br/>
</xsl:for-each>
</xsl:template

Since I get the correct number of "(value here)" lines 
for each bodyblock in the results, the source elements 
are obviously being parsed, but none of the source 
values show up. Am I missing something obvious here? I 
am doing the same thing for other nodes (article, 
bodyblock)and those work fine.

I'm using Forte/JSP for development with SAX as the 
parser.

Thanks,
