I don't have my "tools" here, but from the top of my head, try
something like this:

<xsl:template match="reg">
   <xsl:value-of select="."/>:
   <xsl:value-of select="sum(preceding-sibling::reg/@count)"/>-
   <xsl:value-of
select="sum(preceding-sibling::reg/@count|self::reg/@count)"/>
</xsl:template>
