Your main problem is that you are grouping by all 'payment' but you only want to group by those that have the same parent 'payments' To do that you'll have to change a little your key definition and your for-each call. <!-- you'll need the generate-id(parent::payments) because you want all payment belonging to the same parent --> <xsl:key name="mkey" match="payment[date]" use="concat(generate-id(parent::payments),' ',date)"/> (...) <xsl:template match="parcel"> <br/> ------ <!-- altered for-each --> <xsl:for-each select="payments/payment[generate-id()=generate-id(key('mkey',concat(generat e-id(parent::payments),' ' ,date))[1])]"> <xsl:sort select="date" /> <br/> <!-- here you'll just need to sum the amount of the keys nodeset --> <xsl:value-of select="date"/>::<xsl:value-of select="sum(key('mkey',concat(generate-id(parent::payments),' ' ,date))/amount)"/> </xsl:for-each> </xsl:template> XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
