Sorry. I got a message from someone else that included
the same XSL stylesheet -- or I at least it looked the same.
On closer examination, it had the following
<xsl:sort
order="{$sortorder}"
data-type="text"
select="{$sortcolumn}"/>
<xsl:apply-templates select="."/>
So moving the params to the top with Rechell's
original stylesheet worked, but not with the slightly
modified version I was testing.
Sorry for the confusion.
