G'day David, (well actually it is 10PM) I have only given four days, but in fact there is 40 days (8 weeks). I want to pick off the last 5 days and work out which of those is the smallest. So perhaps, I should say: <xsl:variable name="varL5"> <xsl:for-each select="day[position() > 35 and position() < 41]"> <xsl:sort select="cl" order="descending" data-type="number"/> <xsl:if test="position()=last()"><xsl:value-of select="cl" /></xsl:if> </xsl:for-each> </xsl:variable> I then want to back off a day and get the next five and get the smallest <xsl:variable name="varL51"> <xsl:for-each select="day[position() > 34 and position() < 40]"> <xsl:sort select="cl" order="descending" data-type="number"/> <xsl:if test="position()=last()"><xsl:value-of select="cl" /></xsl:if> </xsl:for-each> </xsl:variable> I then want to back off another day and get the next five and get the smallest <xsl:variable name="varL52"> <xsl:for-each select="day[position() > 33 and position() < 39]"> <xsl:sort select="cl" order="descending" data-type="number"/> <xsl:if test="position()=last()"><xsl:value-of select="cl" /></xsl:if> </xsl:for-each> </xsl:variable> I thought it might be safer(ie data problems would be less) to start at the end as the starting point, that's y I was going to use last(), last()-1, last()-2 for variable varL5, varL51, varL52 respectively What do u think? John You have four day elements so <xsl:for-each select="day[position() > last()-3 and position() < last()-1]"> is <xsl:for-each select="day[position() > 1 and position() < 3]"> The first clause isn't a constraint as position is always greater than 1 so this is <xsl:for-each select="day[position() < 3]"> so you just select the first two days then sort them in descending order of cl and take the last in sorted order, so that would give 6500 You said you wanted 6200 but haven't specified the transform that you want to produce taht so I can't suggest changes to teh xsl.
