Hi Roelof,
    Here are couple of things I can see wrong in the stylesheet you've
posted,

1. you've a variable declaration <xsl:variable name="mycount" ... but
you don't make use of this variable in the stylesheet.

2. you've a template definition
   <xsl:template match="artikel-details/entry">
      <xsl:param name="articleperpage"/>
      ...

which you're seemingly calling as,
<xsl:template match="/">
   <xsl:apply-templates select="/data/artikel-details/entry"/>
     ...

This is wrong, since you don't pass an argument matching the template
parameter. If you need a parameter in this template, then you should
call the template as follows,

<xsl:apply-templates select="/data/artikel-details/entry">
    <xsl:with-param name="articleperpage" select="{provide a value OR
compute}"/>
</xsl:apply-templates>

3. In the template definition,

<xsl:template match="artikel-details/entry">
  ...

you make a call to a named template as follows,

<xsl:call-template name="printdata">
   <xsl:with-param name="articleperpage">
     ...

To handle this template call, it seems you've defined this template,

<xsl:template match="printdata">
  ...

This seems to be wrong. I think, a xsl:template match=".. template
cannot receive a call from <xsl:call-template ... I think you need to
modify the template, <xsl:template match="printdata"> ... to
following,

<xsl:template name="printdata">
   <xsl:param name="articleperpage">
     ...

4. In the template call,

<xsl:call-template name="printdata">
     <xsl:with-param name="articleperpage">
         <xsl:choose>
             <xsl:when test="($month = '2005-02') and (number($page) =
1)">2</xsl:when>
             <xsl:when test="($month = '2005-02') and (number($page) =
2)">3</xsl:when>
             <otherwise>1</otherwise>
          </xsl:choose>
     </xsl:with-param>
</xsl:call-template>

you use variable references $month and $page. these variable
references were not declared before, which is wrong.

so lot of errors!
