Class 我的VBA代码中有错误。内部字典中的函数Show将计数增加1

我创建了两个类。一个具有“double”类型项的内部Dict和一个具有内部Dict类型项的外部Dict。这两个类都有一个显示过程来打印数据。我创建了一个测试过程来验证这两个类。内部记录可以，但外部记录有一个问题：当跟踪进入显示功能时，计数增加1。它使用空键创建一个新项。这在尝试打印新项目时会生成错误

“有什么线索吗？”

解决了。代码我是对的

Vba字典在访问不存在的项时出现问题：Vba使用空键创建空项

代码从不计算不存在的元素，但在监视窗口中，我有一个表达式正在查看字典类型的外部变量。进入模块显示时，观察表达式将添加一项
