Hi Walter,

Doh.  The <xsl:for-each for the data should be *outside* the
row-creation:

 <xsl:for-each select="$data">
    <tr>
       <xsl:variable name="datum" select="events/call_event" />
       <xsl:for-each select="$columns">
          <xsl:variable name="column" select="." />
          <td>
             <xsl:value-of select="$datum/*[name() = $column]" />
          </td>
       </xsl:for-each>
    </tr>
 </xsl:for-each>

i.e. for each bit of data (interaction), create a row.  Within the
row, for each column, create a cell.
 
Cheers,

Jeni
