Greetings!

I've got a little issue with a site I'm building... I don't really understand the problem at the moment.

(using 4.6.1)

<xsl:param name="currentPage"/>
<xsl:template match="/">
  <xsl:choose>  
    <xsl:when test="$currentPage/banners != ''">
         <div class="bannercontainer jcarousel-skin-banner">      
          <xsl:variable name="items" select="umbraco.library:Split($currentPage/banners,',')" /> 
            <div id="slider">
               <xsl:for-each select="$items//value">       
                 <xsl:variable name="media" select="umbraco.library:GetXmlNodeById(.)" />           
                 <xsl:variable name="media2" select="umbraco.library:GetMedia($media/banner_afbeelding, 0)" />
                 <xsl:variable name="url" select="umbraco.library:NiceUrl($media/banner_url)"/>
                 <div class="test">
                   Bannervalue: <xsl:value-of select="./banner_subject"/>
                 </div>
              <xsl:if test="$media2">       
                <a href="{$url}"><img src="{$media2/umbracoFile}" /></a>
              </xsl:if>  
              </xsl:for-each>
          </div>
          <div class="bannershadow"> &nbsp;</div>
        </div>
    </xsl:when>
    <xsl:otherwise>
    </xsl:otherwise>
   </xsl:choose>
</xsl:template>

This is the code i'm using, the idea is as follows:

I've made a datatype:

Name: 'Banner'
Rendercontrol 'ultimate picker' 
Settings: Ntext, CheckBoxList, and a parentnodeid.

The parentnodeid links to a folder in the 'Content' section. Under this folder we've made all kinds of banners with attributes(Tekst, subject, url, image)

In the 'Base' pages document type, I've added this datatype.

So now when I create a new page, I can select a few banners under the 'banner' tab witch are originating from the folder 'Banners'.

Now here's the problem, I can get (some) values from these banners (as you see in the code, the GetMedia and the NiceUrl works) But for example I can't get the subject from this banner... It's just blank!

So...Anyone have any idea's on what I'm doing wrong?
