XSLT Multiple Variables in Concatenate are not Propagating

Variables I have defined are coming through as strings, rather than propagating values.

Source

<?xml version="1.0"?>
<results>
    <result>
        <title_id>
            123456
        </title_id>
        <product_id>
            2
        </product_id>
        <track_id>
            5
        </track_id>
    </result>
</results>

XSL

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

 <body>
 <table border="1" cellpadding="4" cellspacing="0">
 <tr bgcolor="#fb0006" align="center">
  <td><b>Link</b></td>
</tr>

 <xsl:for-each select="//results/result">

 <xsl:variable name="titlevar" select="title_id" />
 <xsl:variable name="productvar" select="product_id" />
 <xsl:variable name="trackvar" select="track_id" />


 <tr>
  <td><a href="{concat('http://www.myaddress/', '$titlevar', '-', '$productvar', '/?', '$trackvar')}" target="_blank">link</a></td>
 </tr>

 </xsl:for-each>

 </table>
 </body>
 </html>

Outputs: http://www.myaddress/$titlevar-$productvar/?$trackvar What I want is: http://www.myaddress/123456-5/?2. I have tried all manner of brackets, apostrophes and speech marks. Can anyone see why it's not working?

There should be no quote marks surrounding the variable references. Also note the use of normalize-space().

This works:

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

  <body>
    <table border="1" cellpadding="4" cellspacing="0">
      <tr bgcolor="#fb0006" align="center">
    <td><b>Link</b></td>
      </tr>

      <xsl:for-each select="//results/result">

    <xsl:variable name="titlevar" select="normalize-space(title_id)" />
    <xsl:variable name="productvar" select="normalize-space(product_id)" />
    <xsl:variable name="trackvar" select="normalize-space(track_id)" />

    <tr>
      <td><a href="{concat('http://www.myaddress/', 
                    $titlevar, '-', $productvar, '/?', $trackvar)}" 
             target="_blank">link</a></td>
    </tr>

      </xsl:for-each>

    </table>
  </body>
</html>

You need to remove the quotes around the variables:

<tr>
 <td><a href="{concat('http://www.myaddress/', $titlevar, 
                      '-', $productvar, '/?', $trackvar)}" 
        target="_blank">link</a></td>
</tr>
