Hi David, > Ok, here is a sample of what's going on (a bit dumbed down for brevity): > > <xsl:variable name="cr_amt" > select="/Transactions/Transaction/CreditAmount"/> > <xsl:variable name="cr_under_amt" select="MinAmt/CRUnderMinAmt"/> > > <td style="text-align:right;"> > <xsl:call-template name="displaycurrency"> > <xsl:with-param name="node" select="$cr_amt + $cr_under_amt"/> > <xsl:with-param name="total">1</xsl:with-param> > </xsl:call-template> > </td> > > Then inside "displaycurrency": > > <xsl:variable name="output"> > <xsl:value-of select="sum($node)"/> > </xsl:variable> > > The $total xsl:param tells the template to prepend the currency code > to the value (we only show currency code for totals). The reason for > the sum() is that I can pass either a single node or a node-set. I > always want to sum a node-set that is passed to the template. I > tried this: > > select="$cr_amt | $cr_under_amt" > > But that didn't work. Hmm... that's weird. If the call looks like: <xsl:call-template name="displaycurrency"> <xsl:with-param name="node" select="$cr_amt | $cr_under_amt"/> <xsl:with-param name="total">1</xsl:with-param> </xsl:call-template> then assuming that $cr_amt and $cr_under_amt are node sets containing CreditAmount and CRUnderMinAmt elements as you've said, the $node parameter should be a node set and the sum($node) function should provide you with the sum of those nodes. In what way didn't it work? Did you get an error message, or just not the result that you expected to see? > Also, there is one additional requirement, when I pass a node into > the template like this: > > <td align="right"> > <xsl:call-template name="displaycurrency"> > <xsl:with-param name="node" select="$cr_under_amt"/> > <xsl:with-param name="total">1</xsl:with-param> > </xsl:call-template> > </td> > > The node has two attributes, @currency_code and @minor_unit (you've > seen these in my last thread).

You're passing the node itself, so you can do anything to it you can normally do - get its attributes, children, ancestors, whatever you need.
