Your problem lies somewhere else, which is not possible to tell without having your
code available.

Below is an example of using the sum function:

xml source:
----------
<elements>
  <element count="2" />
  <element count="1" />
  <element count="4" />
  <element count="3" />
</elements>


stylesheet:
----------
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
  <xsl:output method="text" />

  <xsl:template match="/">
    <xsl:value-of select="sum(elements/element/@count)" />
  </xsl:template>
</xsl:stylesheet>

Result:
------
10
