XSLT Sum help

[diablokicks]

I need help getting the sum of two attributes

EURO TOTAL: $
  <xsl:for-each select="Books/Book/price[@currency='Euros']" >
<xsl:value-of select="."/>
<xsl:text>&#x0d;&#x0a;</xsl:text>
 </xsl:for-each>
  <xsl:for-each select="Books/Book" >
  <xsl:value-of select="sum(/price[@currency='Euros'])"/>

  </xsl:for-each>

I'm trying to sum the Euro's, but it is only showing 0's.
What am i missing?

the sum() syntax looks right, so it must be something wrong with the XPATH

try:
sum(price[@currency='Euros'])
without the "/" at the beginning
