Conditional display of subtotal element

Hi,
I've combined info from an archived thread to generate
subtotals and totals (thanks, Jeni). My problem now is
that there's a requirement for only the first date heading
for a subtotal to be shown. The first report listing is
what I'd like, the second is what I'm currently getting.
Following the report examples are the xml file and the
xsl. I'm looking for suggestions for how to show or not
show the date based on if it's the first one for this
grouping.

Thanks!
-Steve
