在groupheader进行汇总,能显示汇总金额才怪
打印groupheader上的memo内容时,你的数据都还未出来呢!!!

就好像你在Report Title上放汇总一样的道理,SUM中的数据未打印前总是0;

要实现这种效果,可以在GetValue事件中,通过代码来预先统计赋值;

赋值没用啊 groupfooder上的memo有值正确显示，但赋给groupheader上的memo，还是显示0

直接在组标头区[SUM([DMHZFYCX.Query1."ssje"])]应该是不行的
试试将groupfooder带区的memo汇总值赋给groupheader上的一个memo，是否可行

groupheader上汇总金额的memo中 [SUM([DMHZFYCX.Query1."ssje"])] 这样写的，可结果总是0
在groupfooder 中这样就可以 郁闷

groupheader中要实现这样的求和 该怎么写 ？？？？？要设置什么属性还是要在OnBeforePrint 中写代码 ？
