Altova : Altova Mailing List Archives

Hi I am using XSL Version 2 I am trying to use this code to add a value (say 100) to the variable summation <xsl:variable name="summation">0</xsl:variable> <xsl:template match="csv:csv"> <xsl:element name="csv:csv"> <xsl:for-each select="/csv:csv/csv:line"> <xsl:variable name=" summation " select="$summation + 100"/> <xsl:value-of select="$summation "/> </xsl:for-each> </xsl:element> </xsl:template> The value printed by value-of statement is always 100. I need the variable summation to accumulate the values added to it thanks in advance Mahmoud
