crystal-reports - Crystal 报表中的全局变量

Question

我试图在 Crystal Reports 中保持教师、支持人员和经理的运行总数，我决定使用全局变量来做到这一点，我知道可以通过其他方式实现，但我想提供全局变量变量一个去。

    WhileReadingRecords;
Global NumberVar TotalSManagement;
Global NumberVar TotalSTeachers;
Global NumberVar TotalSSupport;
Global NumberVar TotalLManagement;
Global NumberVar TotalLTeachers;
Global NumberVar TotalLSupport;

if{staff_addresses_txt.Staff category} = "MANA" and {staff_addresses_txt.Name} = "CTK:Lewisham" then
    TotalLManagement = TotalLManagement + 1
else
if{staff_addresses_txt.Staff category} = "TEAC" and {staff_addresses_txt.Name} = "CTK:Lewisham" then
    TotalLTeachers = TotalLTeachers + 1
else
if{staff_addresses_txt.Staff category} = "SUPP" and {staff_addresses_txt.Name} = "CTK:Lewisham" then
    TotalLSupport = TotalLSupport + 1
else
if{staff_addresses_txt.Staff category} = "MANA" and {staff_addresses_txt.Name} = "CTK:St Mary's" then
    TotalSManagement = TotalSManagement + 1
else
if{staff_addresses_txt.Staff category} = "TEAC" and {staff_addresses_txt.Name} = "CTK:St Mary's" then
    TotalSTeachers = TotalSTeachers + 1
else
if{staff_addresses_txt.Staff category} = "SUPP" and {staff_addresses_txt.Name} = "CTK:St Mary's" then
    TotalLSupport = TotalLSupport + 1;

if 语句肯定会触发，但是当我使用以下代码在页面底部显示总计时，一切都是 0.00:

Global NumberVar TotalSManagement;
Global NumberVar TotalSTeachers;
Global NumberVar TotalSSupport;
Global NumberVar TotalLManagement;
Global NumberVar TotalLTeachers;
Global NumberVar TotalLSupport;

if {staff_addresses_txt.Name} = "CTK:Lewisham" then
 "[Lewisham] Managers: " & TotalLManagement & " | Teachers: " & TotalLTeachers & " | Support: " & TotalLSupport
else
 "[Sidcup] Managers: " & TotalSManagement & " | Teachers: " & TotalSTeachers & " | Support: " & TotalSSupport

制作这个: [Lewisham] 经理:0.00 |教师:0.00 |支撑:0.00

我是否错误地使用了全局变量？我试过用其他数字初始化它们，但响应总是一样的。有什么想法吗？

您永远不会为变量分配任何值。 “:=”是赋值运算符，不是“=”。另外，为了安全起见，页脚公式应该有 WhilePrintingRecords；在顶部。
