As you can see we have all types of cars. Now they all have a total price. What I've done so far is this. 

<?xml version="1.0" encoding="UTF-8"?>

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

<xsl:template match="/autoads">
 <html>
  <body>
    <h2>Bilar</h2>
    <table border="1">
      <tr bgcolor="#9acd32">
        <th>Antal Äldre än 1999</th>
        <th>Antal Yngre än 1999</th>
        <th>Antal Automat</th>
        <th>Antal Ej Automat</th>
        <th>Genomsnitts pris för bilar äldre än 19999</th>
        <th>Genomsnitts pris för bilar ungre än 19999</th>
      </tr>
      <tr>
         <td><xsl:value-of select="format-number(count(ad[regyear &lt;= '1999']), '0')"/> </td>
         <td><xsl:value-of select="format-number(count(ad[regyear &gt;= '1999']), '0')"/></td>
           <td>
            <xsl:value-of select="format-number(count(ad[contains(adtext, 'automatic')]), '0')"/>
           </td>
           <td>
           <xsl:value-of select="format-number(count(ad[not(contains(adtext, 'automatic'))]), '0')"/>   
           </td>
           <td><xsl:value-of select="format-number(sum(ad[regyear &lt;= '1999']/price), '0.00')"/></td>
        <td><xsl:value-of select="format-number(sum(ad[regyear &gt;= '1999']/price), '0.00')"/></td>
       </tr>


      </table>
  </body>
  </html>
  </xsl:template>
</xsl:stylesheet>

But the above does not count out the average price, I've tried to use the whole count of the cars like this

   <xsl:variabel name="carsbelow19" select="format-number(count(ad[regyear &lt;= '1999']), '0')"/>
   <xsl:variabel name="carsabove19" select="format-number(count(ad[regyear &gt;= '1999']), '0')"/>

And then use them as this

<td><xsl:value-of select="format-number(sum(ad[regyear &lt;= '1999'] div $carsbelow19), '0.00')"/></td>

But this gives me an error. So I dont think that I can use the whole variabel and link the existing cars as a "div".

Does someone know a solution or can point me in the right direction? Thanks!

    NOTE: You are including the year 1999 in both variables. I believe you need to remove the = from one of them.
