Hi everyone, I know my xslt is pretty lame still but I am trying!

<!-- Renders the list containing the Documents -->
  <xsl:template name="RenderNodes">
    <xsl:param name="documents" />
    <xsl:param name="page" />
    <xsl:param name="numDisplay" />

    <xsl:variable name="startPosition" select="($page * $numDisplay - $numDisplay) + 1" />
    <xsl:variable name="endPosition" select="$page * $numDisplay" />
<div id="list-wrapper">
<ul class="list">
 <xsl:for-each select="$documents">
  <xsl:sort select="./@createDate" order="descending" />
<li>



<xsl:choose>
    <xsl:when test="position() &gt;= $startPosition and position() &lt;= $endPosition">
   <xsl:variable name="focusImage" select="./data [@alias = 'PreviewImage1']"/>
            <xsl:if test="string($focusImage) != ''">
              <xsl:variable name="mediaId" select="$focusImage" />
              <xsl:if test="$mediaId &gt; 0">
                <xsl:variable name="media" select="umbraco.library:GetMedia($mediaId, false)" />
                    <a href="{umbraco.library:NiceUrl(./@id)}"><img alt="{$media/@nodeName}" src="{$media/data [@alias = 'umbracoFile']}" width="250" /></a>
              </xsl:if>
            </xsl:if>
<p><a href="{umbraco.library:NiceUrl(./@id)}"><xsl:value-of select="@nodeName"/></a></p>
</xsl:when>
<xsl:otherwise>-----ROLLBACK IMAGE IN HERE-----</xsl:otherwise>
</xsl:choose>



</li>
      </xsl:for-each>
    </ul>
</div>


  </xsl:template>

I am trying to insert a rollback image in this list if there is no image present in the content section (I select an image via the media picker).

I have tried all sorts of combos but I really need some proper help from someone who understands what each bit of the code does. I have so far worked out that moving the variables outside of the <xsl:choose> does not render the list properly, and theat <xsl:when> cannot be a child of <xsl:when> etc etc..anyway, that's propbably very basic to you guys. I have adapted this from the runway news xslt so credit to Kim Løwert :)

Thanks if anyone can shed some light on this. I just don't know in which order to put this stuff. I imagine it's all over the place! On a plus note, it works perfectly when useing <xsl:if> statements rather than choose, whens and otherwise...

Perhaps there is a better way? Or maybe I'm on the right track, not sure :(

Regards,

Sam.
