Crystal reports Crystal报告组摘要的总和

我有一份报告，其中我试图将一个小组的总结总结给另一个小组。例：

   group 1: 75         <- sum of the maximums 
       group 2: 50     <- max of the group
           line 1: 50
           line 2: 40
           line 3: 10
       group 2: 25     <- max of the group
           line 1: 10
           line 2: 2
           line 3: 25

---

Group1:75如果必须在Group1头中包含该值，那么我认为您唯一的选择将是SQL表达式

Group1页脚会容易得多。要点是，您可以简单地使用一个变量跟踪最大值之和

//Place this formula in the Group1 Header
whileprintingrecords;
numbervar g1sum := 0;

//Place this formula in the Group2 Footer
whileprintingrecords;
numbervar g1sum;
g1sum := g1sum + maximum({table.value},{table.group2_field})

//Place this formula in the Group1 Footer
whileprintingrecords;
numbervar g1sum;

我想我可以把摘要记在页脚。谢谢效果很好
