Hi,

I am using the following xslt to return a list of demonstration dates at our shops, which are then ordered into 5 results per page.

<xsl:param name="currentPage"/>

<xsl:variable name="perpage" select="number('5')"/>
<xsl:variable name="pageNumber">
  <xsl:choose>
    <xsl:when test="umbraco.library:RequestQueryString('page') &lt;= 0 or string(umbraco.library:RequestQueryString('page')) = '' or string(umbraco.library:RequestQueryString('page')) = 'NaN'">0</xsl:when>
    <xsl:otherwise>
      <xsl:value-of select="umbraco.library:RequestQueryString('page')"/>
    </xsl:otherwise>
  </xsl:choose>
</xsl:variable>

<xsl:template match="/">

  <xsl:variable name="demoType" select="umbraco.library:GetPreValues('6646')"/>
  <select>
    <xsl:for-each select="$demoType//preValue">
      <option value="{@id}">
        <xsl:value-of select="current()"/>
      </option>
    </xsl:for-each>
  </select>

  <xsl:variable name="demonstrators" select="umbraco.library:GetPreValues('6632')"/>
  <select>
    <xsl:for-each select="$demonstrators//preValue">
      <option value="{@id}">
        <xsl:value-of select="current()"/>
      </option>
    </xsl:for-each>
  </select>

  <xsl:variable name="demoRegion" select="umbraco.library:GetPreValues('6649')"/>
  <select>
    <xsl:for-each select="$demoRegion//preValue">
      <option value="{@id}">
        <xsl:value-of select="current()"/>
      </option>
    </xsl:for-each>
  </select>

  <xsl:variable name="demoslist" select="umbraco.library:GetXmlAll()//Demonstration [@isDoc]"/>
  <xsl:if test="$demoslist">

    <xsl:for-each select="$demoslist">
      <xsl:sort select="umbraco.library:FormatDateTime(demoDate, 'yyyyMMdd')" order="ascending"/>
      <xsl:if test="position() &gt; $perpage * number($pageNumber) and position() &lt;= number($perpage * number($pageNumber) + $perpage)">

        <xsl:value-of select="umbraco.library:FormatDateTime(demoDate, 'dd/MM/yyyy')" /><br/>
        <xsl:value-of select="umbraco.library:FormatDateTime(demoDate, 'h:mm tt')" /> - <xsl:value-of select="umbraco.library:FormatDateTime(demoDate, 'h:mm tt')" /><br/>
        <xsl:value-of select="../@nodeName"/> <br/> <xsl:value-of select="demoType" /> with <xsl:value-of select="demonstrator" /><br/>
        <xsl:value-of select="demoOtherNotes" />

      </xsl:if>
    </xsl:for-each>

    <xsl:if test="count($demoslist) &gt; $perpage">
      <ul class="search-results-pagination">
        <xsl:call-template name="for.loop">
          <xsl:with-param name="i">1</xsl:with-param>
          <xsl:with-param name="page" select="$pageNumber + 1"></xsl:with-param>
          <xsl:with-param name="count" select="ceiling(count($demoslist) div $perpage)"></xsl:with-param>
        </xsl:call-template>
      </ul>
    </xsl:if>
  </xsl:if>
</xsl:template>

<xsl:template name="for.loop">
  <xsl:param name="i"/>
  <xsl:param name="count"/>
  <xsl:param name="page"/>
  <xsl:if test="$i &lt;= $count">
    <li>
      <a href="{umbraco.library:NiceUrl($currentPage/@id)}?page={$i - 1}">
        <xsl:attribute name="class">
          <xsl:if test="$i = 1">
            <xsl:value-of select="'first '"/>
          </xsl:if>
          <xsl:if test="$page = $i">
            <xsl:value-of select="'selected '"/>
          </xsl:if>
        </xsl:attribute>
        <xsl:value-of select="$i" />
      </a>
    </li>
  </xsl:if>
  <xsl:if test="$i &lt;= $count">
    <xsl:call-template name="for.loop">
      <xsl:with-param name="i">
        <xsl:value-of select="$i + 1"/>
      </xsl:with-param>
      <xsl:with-param name="count">
        <xsl:value-of select="$count"/>
      </xsl:with-param>
      <xsl:with-param name="page">
        <xsl:value-of select="$page"/>
      </xsl:with-param>
    </xsl:call-template>
  </xsl:if>
</xsl:template>

What I would like to be able to do is filter these results based on selections made from a number of drop down lists. I have managed to create the lists, populating the data from datatypes but I am unsure how I can apply these selections to a search.

Code for populating lists...

<xsl:variable name="demoType" select="umbraco.library:GetPreValues('6646')"/>
<select>
  <xsl:for-each select="$demoType//preValue">
    <option value="{@id}">
      <xsl:value-of select="current()"/>
    </option>
  </xsl:for-each>
</select>

<xsl:variable name="demonstrators" select="umbraco.library:GetPreValues('6632')"/>
<select>
  <xsl:for-each select="$demonstrators//preValue">
    <option value="{@id}">
      <xsl:value-of select="current()"/>
    </option>
  </xsl:for-each>
</select>

<xsl:variable name="demoRegion" select="umbraco.library:GetPreValues('6649')"/>
<select>
  <xsl:for-each select="$demoRegion//preValue">
    <option value="{@id}">
      <xsl:value-of select="current()"/>
    </option>
  </xsl:for-each>
</select>

Can anyone help me out?

Thanks
