Change this to <xsl:variable name="firstN" select="@Attendance"/>

That's because your firstN is a text node with white spaces before the
number, some xsl processors pass those as string instead of number
A tweak would be to use <xsl:with-param name="firstN"
select="number($firstN)"/> to force it to be a number
