Hi Kathryn,

Use:


<xsl:for-each select="//brpfields/record[@*[name()=$param1] >'0']">
  <xsl:sort data-type="number" select="@*[name()=$param1]"/>
  ..........
</xsl:for-each>


I find the following a little bit simpler:

<xsl:for-each select="//brpfields/record/@*[name()=$param1][. >'0']">
  <xsl:sort data-type="number" select="."/>
  ..........
</xsl:for-each>
