I have an xslt fiel with the following XSLT inspired from a recent thread.

Somehow it dosent insert the picture as i expect.

I have boiled it down to the choose statement. I doesent seem to get the property from the page (Property named billede, is a mediapicker)

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE xsl:stylesheet [ <!ENTITY nbsp "&#x00A0;"> ]>
<xsl:stylesheet
    version="1.0"
    xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
    xmlns:msxml="urn:schemas-microsoft-com:xslt"
    xmlns:umbraco.library="urn:umbraco.library" xmlns:Exslt.ExsltCommon="urn:Exslt.ExsltCommon" xmlns:Exslt.ExsltDatesAndTimes="urn:Exslt.ExsltDatesAndTimes" xmlns:Exslt.ExsltMath="urn:Exslt.ExsltMath" xmlns:Exslt.ExsltRegularExpressions="urn:Exslt.ExsltRegularExpressions" xmlns:Exslt.ExsltStrings="urn:Exslt.ExsltStrings" xmlns:Exslt.ExsltSets="urn:Exslt.ExsltSets" xmlns:umbsql="urn:umbsql" xmlns:myExt="urn:myExt"
    exclude-result-prefixes="msxml umbraco.library Exslt.ExsltCommon Exslt.ExsltDatesAndTimes Exslt.ExsltMath Exslt.ExsltRegularExpressions Exslt.ExsltStrings Exslt.ExsltSets umbsql myExt ">


<xsl:output method="xml" omit-xml-declaration="yes"/>

<xsl:param name="currentPage"/>

<xsl:template match="/">

<!-- start writing XSLT -->
<xsl:variable name="picID">
          <xsl:choose>
           <xsl:when test="data[@alias='billede'] != ''"><xsl:value-of select="data[@alias='billede']" /></xsl:when>
           <xsl:otherwise>2138</xsl:otherwise>
          </xsl:choose>
</xsl:variable>

<xsl:if test="$picID != '' ">

    <img>
        <xsl:attribute name="src">
            <xsl:value-of select="umbraco.library:GetMedia($picID, false)/data [@alias = 'umbracoFile']" />
            </xsl:attribute>
    </img>
</xsl:if>

</xsl:template>

</xsl:stylesheet>

i tried to use string(data[@alias='billede'])  but that doesent change anything. I doublechecked spelling of property names and also checked that a picture is actually selected with the media picker, but still no go.

I have a feeleing that i'm overlooking some stupid mistake.
