RE: Calculating Sum in XSLT 1.0

will this work with xalan? because i tried to use
something like this and it gave me an error. 

also i tried using this
<xsl:template match="currentnode"
...
...

<xsl:variable name="Total">
        <xsl:for-each
select="preceding-sibling::sibling[(_at_)value]">
            <SubTotal>
              <xsl:value-of select="(@value)"/>
            </SubTotal>
          </xsl:for-each>
</xsl:variable>

<p>
  <xsl:value-of
select="sum(xalan:nodeset($Total)/SubTotal)"/>
<br/>
</p>

</xsl:template>

and it gives me an error 

"function not in namespaceError in Xpath expression,
function not in namespace"

Please let me know.
Thanks,
Abhi
