I modified the code slightly:

<xsl:variable name=3D"format-string">
	<xsl:text>#,##0</xsl:text>
	<xsl:choose>
		<xsl:when test=3D"$currency_code/@minor_unit > 0">
			<xsl:text>.</xsl:text>
			<xsl:call-template name=3D"minor_unit">
				<xsl:with-param name=3D"minor_unit" select=3D"$currency_code/@minor_uni=
t"/>
			</xsl:call-template>
		</xsl:when>
	</xsl:choose>
</xsl:variable>

I just added the xsl:choose because I was getting a decimal point when mino=
r_unit was zero (for Yen for example).
Thanks again, and if you are ever in NYC, I owe you a beer.
