Hi Wendell!

Thanks so much for the help, I attempted your
suggestion, but I am getting an empty string returned
with no results???? By the way I am using XSLT v1.0


---I implemented the key as follows----:
<xsl:key name="itemsbydistributor"
match="ItemAsSold[CanOrderFlag='true'][CanShipFlag =
'true']" use="DistributorCode"/>


--then down within the XSL file i have----:
<xsl:variable name="distributorVal">	
<!-- only process distributorCodes if canShip and
canOrder are both true -->
   <xsl:for-each
select="//DistributorCode[generate-id(parent::ItemAsSold)=generate-id(key('itemsbydistributor',current())[1])
]">
        <xsl:value-ofselect="DistributorCode"/>
        <xsl:text>,</xsl:text>
   </xsl:for-each>
</xsl:variable>
