Lindy Quick, I composed this before I saw Goetz Beck's reply to your post, but I think this is complementary to what he said, so I'm still going to send it You wrote that you wanted to determine "for each the minimum and maximum value of each whole-request, sub-request, and another-request. I have tried to determine the Whole Request maximum, using xsl:call-template to put it in the proper <td> of my table <xsl:template name="WholeRequestMax"> <xsl:variable name="max"> <xsl:for-each select="row/whole-request"> <xsl:sort data-type="number" order="descending"/> <xsl:if test="position()=1"> <xsl:value-of select="."/></xsl:if> </xsl:for-each> </xsl:variable> </xsl:template> However, I return no data and my <td> is empty, can anyone tell me what I am doing wrong?" The basic strategy for finding a maximum by sorting and taking the first element is sound (so long as the number of rows doesn't get too large), and has been discussed on the list before. So why doesn't it work here? You don't really tell us enough about the context to be sure, but here are some of the possibilities: 1. There is no <td> in the snippet of xsl that you gave us, so your variable "max" is going out of scope before you use it (assuming that you wanted to use it in the template from which you called "WholeRequestMax"). 2. Remember that calling a named template does not change the current node. So the current node must be the parent of your rows (which is <profile-table> in your example. Otherwise the for-each will return nothing at all. If these don't put you on the right track, try posting a little more of your xslt. I hope this helps.
