I know somebody must have already answered this
question.
I am using sum function with RTF. The declaration of
my RTF is
<xsl:variable name="purchaseTotalLength">
<xsl:for-each
select="exslt:node-set($purchaseTotalcount)/*">
	<xsl:copy>
		<xsl:copy-of select="@val"/>
	</xsl:copy>
</xsl:for-each>
</xsl:variable>
 and My intention is to sum all @val values so that I
am using 
<xsl:value-of
select="sum(exslt:node-set($purchaseTotalLength))"/>

But the above display gives NAN
I too tried with 
<xsl:value-of
select="sum(exslt:node-set($purchaseTotalLength)/*)"/>
but still I got NAN.
Any input?

regards,
Ranjan
