crystal报表中的全局变量

Question

我试图在crystal reports中保持教师、支持人员和管理人员的总数，我决定使用全局变量来实现这一点，我知道用其他方法也是可能的，但我想让全局变量试试。

    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:路易斯汉姆管理人员: 0.00 |教师: 0.00 |支持: 0.00

我是不是错误地使用了全局变量？我尝试用其他数字初始化它们，但响应总是相同的。有什么想法吗？

你永远不会给你的变量赋值。":=“是赋值操作符，而不是"=”。另外，为了安全起见，页脚公式的顶部应该有WhilePrintingRecords；。
