Complain to your XSLT processor vendor (or switch to a different processor), and change your code to: <xsl:variable name="result"> <xsl:choose> <xsl:when test="$next > $last"> <xsl:value-of select="$last"/> </xsl:when> <xsl:otherwise> <xsl:value-of select="$next"/> </xsl:otherwise> </xsl:choose> </xsl:variable> <xsl:value-of select="concat('slide',$result,'.html')"/> Michael Kay
