You haven't said where you added this. Since the error message was "variable
out of scope", you presumably didn't add it within the scope of the
$subtotals variable.

But there are two other problems. Firstly, you've declared the variable as a
result tree fragment, and are then trying to get inside it using a path
expression. You can't do this without the node-set() extension. Why not just
declare the variable as <xsl:variable name="subtotals" select="Total"/>

But that leads to the question, what do you expect to output as the
"subtotal"? I can't see where you are doing any calculation of a subtotal.
