I have a form and list module in one page of my DNN site-
The module holds the Title and URL of articles, along with the date they were published and the name of the professor involved.
I have used XSL to extract the URL from the page chosen, and generated <a href="url">title</a>'s of the grid. Everything seems to be going fine so far, but I the method for sorting by Date has eluded me.

This is my XSL code

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:udt="DotNetNuke/UserDefinedTable" exclude-result-prefixes="udt">
  <xsl:output method="xml" indent="yes" omit-xml-declaration="yes" />
  <!--
  This prefix is used to generate module specific query strings
  Each querystring or form value that starts with udt_{ModuleId}_param
  will be added as parameter starting with param
  -->
  <xsl:variable name="prefix_param">udt_<xsl:value-of select="//udt:Context/udt:ModuleId" />_param</xsl:variable>

  <xsl:template match="udt:Data" mode="list">
    <tr class="Normal">
      <td>
        <xsl:call-template name="EditLink" />
      </td>
      <td>
        <a href="{udt:Link_UDT_Url}" target="_blank">
          <xsl:value-of select="udt:Title" disable-output-escaping="yes" />
        </a>
      </td>
      <td>
        <xsl:value-of select="udt:Date_UDT_Value" disable-output-escaping="yes" />
      </td>
      <td>
        <xsl:value-of select="udt:Professor" disable-output-escaping="yes" />
      </td>
    </tr>
  </xsl:template>

  <xsl:template match="/udt:UserDefinedTable">
    <xsl:variable name="currentData" select="udt:Data" />
    <xsl:if test="$currentData">
      <table>
        <xsl:apply-templates select="$currentData" mode="list">
        </xsl:apply-templates>
      </table>
    </xsl:if>
  </xsl:template>

  <xsl:template name="EditLink">
    <xsl:if test="udt:EditLink">
      <a href="{udt:EditLink}">
        <img border="0" alt="edit" src="{//udt:Context/udt:ApplicationPath}/images/edit.gif" />
      </a>
    </xsl:if>
  </xsl:template>
</xsl:stylesheet>

I have tried to insert <xsl:sort> in various places (according to other threads in this forum) but none of them have worked. Quite often, they'd fill the first page or so with gibberish, with the graph at the end, still unsorted.

Am I just placing the <xsl:sort> in the wrong place?
