使用XSLT对分组XML工作流中的数据求和

我试图在XSLT中创建一个类积分的总和，但我不知道将sum语句放在哪里

以下是我创建的sum语句：

   <credit-sum><xsl:value-of select='format-number(sum(CRSMINCRED1),"##")'/></credit-sum>

我只想计算“必修”课程的学分。但当我把sum语句放进去时，它只是单独显示每个类的总数，而不是类组

以下是XSLT：

课程组

模板就是进行此更改的地方：

  <xsl:template name="CourseGroup">
    <xsl:param name="courses" />
    <xsl:param name="title" />
    <xsl:param name="requiredCourses" select="false()" />

    <xsl:if test="$courses">
