Well, there are more than one solution, depending on your context node.
Here is one:

<xsl:template match="Borrower">
   <xsl:value-of select="FirstName" />
   <xsl:text> </xsl:text>
   <xsl:value-of select="LastName" />
   <xsl:text>&#xA;Total Assets:  $</xsl:text>
   <xsl:value-of select="sum(AssetSet/Asset/Amount)" />   <!-- here -->
   <xsl:text>&#xA;</xsl:text>
</xsl:template>


To choose a borrower use something like

<xsl:apply-template select="Borrower[Rank=1]" />

Hope that helps,
Oliver
