I am trying to create a list of items, that will only list a specific number of items per page. I have created this XSLT for the purpose:

<xsl:param name="currentPage"/>

<xsl:variable name="itemsPerPage" select="5"/>
<xsl:variable name="numberOfItems" select="count($currentPage/* [@isDoc and string(umbracoNaviHide) != '1'])"/>
<xsl:variable name="pageNumber">  
  <xsl:choose>
      <xsl:when test="umbraco.library:RequestQueryString('page') = ''">
        <xsl:value-of select="1"/>
    </xsl:when>
    <xsl:otherwise>
      <xsl:value-of select="umbraco.library:RequestQueryString('page')"/>
    </xsl:otherwise>  
  </xsl:choose>  
</xsl:variable>   
     
<xsl:template match="/">

<!-- The fun starts here -->
<ul class="albums">

  <xsl:for-each select="$currentPage/* [@isDoc and string(umbracoNaviHide) != '1']">
  <xsl:if test="position() &gt; $itemsPerPage * number($pageNumber -1) and
    position() &lt;= number($itemsPerPage * number($pageNumber -1) * $itemsPerPage)">
    <li>
      <a class="fancybox" data-fancybox-group="group" href="{fullSize}">
        <xsl:attribute name="data-fancybox-group"><xsl:value-of select="$currentPage/@nodeName"/></xsl:attribute>
        <img class="vintage" src="/images/vintage.png"/>
        <img src="{thumbnail}"/>
      </a>
    
    </li>
  </xsl:if>

</xsl:for-each>
  
</ul>

But I doesn't seem to work... I am using Umbraco 4.7. Is it a scheme problem or?

Can anyone tell me what I am doing wrong?
