umbraco.library:GetMedia problem

I dont understand why I get an error in this kode.
If I ignore errors it works fine.

The code looks lige this

<?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" 
  exclude-result-prefixes="msxml umbraco.library Exslt.ExsltCommon Exslt.ExsltDatesAndTimes Exslt.ExsltMath Exslt.ExsltRegularExpressions Exslt.ExsltStrings Exslt.ExsltSets ">


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

<xsl:param name="currentPage"/>

<xsl:template match="/">

<xsl:variable name="media" select="umbraco.library:GetMedia($currentPage/testBillede, 0)" />
 <xsl:if test="$media != ''">
        <xsl:variable name="url" select="$media/umbracoFile" />
        <xsl:variable name="width" select="$media/umbracoWidth" />
        <xsl:variable name="height" select="$media/umbracoHeight" />
        <img src="{$url}" width="{$width}" height="{$height}" />
 </xsl:if>

</xsl:template>

</xsl:stylesheet>

And the error like this

Error occured

Hope that someone can explain it for me :-)

Thanks

just add a check

<xsl:if test="number($currentPage/testBillede) > 0">

it's just alerting you to the fact that as testBilleded could well be empty or not an int...

Do you mean like this:

<xsl:if test="number($currentPage/testBillede) &gt; 0">
        <xsl:variable name="url" select="$media/umbracoFile" />
        <xsl:variable name="width" select="$media/umbracoWidth" />
        <xsl:variable name="height" select="$media/umbracoHeight" />
        <img src="{$url}" width="{$width}" height="{$height}" />
 </xsl:if>

That still gives me an error

I thourght I did check by doing like this:

<xsl:iftest="$media != ''">

If I just have this in my xslt it still fails:

Okay, I got it :-)

<xsl:template match="/">
   <xsl:if test="number($currentPage/testBillede) &gt; 0">
     <xsl:variable name="media" select="umbraco.library:GetMedia($currentPage/testBillede, 0)" />
    
      <xsl:if test="$media">
          <xsl:variable name="url" select="$media/umbracoFile" />
         <xsl:variable name="width" select="$media/umbracoWidth" />
          <xsl:variable name="height" select="$media/umbracoHeight" />
            <img src="{$url}" width="{$width}" height="{$height}" />
        </xsl:if>
   </xsl:if>

</xsl:template>

Thanks Mike
