<xsl:template match="/">
  <html>
  <body>
  <h2>Student Details</h2>
  <table border="1">
    <tr bgcolor="green">
      <th>FIRSTNAME</th>
      <th>LASTNAME</th>
      <th>DOB</th>
      <th>LOCATION</th>
    </tr>


    <xsl:for-each select="details/student">
    <xsl:sort select="firstname"/>
   <tr>


      <td><xsl:value-of select="firstname"/></td>
      <td><xsl:value-of select="lastname"/></td>
      <td><xsl:value-of select="dob"/></td>
      <td><xsl:value-of select="location"/></td>
     </tr>
    </xsl:for-each>
  </table>
  </body>
  </html>
</xsl:template>

</xsl:stylesheet>

FYI, variables in XSLT don't vary, so there is no way to increment a variable (unless you count recursion...). But as you can see there are usually ways to get equivalent functionality. — LarsH

With you current implementation you should be able to use:

<td><xsl:value-of select="position()"/></td>

within the xsl:for-each loop to output a number which will increase for every iteration.
