PowerShell:变量在userform中丢失其值

我有一个带有userform的脚本，您可以使用它编辑广告用户对象

该脚本直接在我们的服务器上运行良好，但当我尝试使用管理员权限从系统中运行它时，

New PSSession

和一些

Invoke Command

的必要变量正在丢失它们的值

这是我的代码（有些东西已经被审查过了）：

我的userform中有两个选项。用户输入数据后，必须通过单击“验证”来验证数据。如果一切正常，按钮“确认”被激活，广告用户对象可能被更改

然而，在验证数据并单击“确认”之后，所有必要的变量都丢失了它们的值，我不知道为什么

正如您在下面看到的，所有设置都是在验证数据之后设置的，但是当我尝试确认它时，所有值都消失了

当脚本直接在我们的广告服务器上运行时，它与现在一样工作正常。我所做的只是通过添加一个远程会话和

Invoke命令来尝试通过我的系统运行它。这真的是个问题吗

感谢您的帮助。
尝试将变量添加到父范围。您可以使用Set变量并将作用域设置为1来执行此操作。非常感谢。现在可以了。您知道为什么脚本直接在服务器上运行时，这是必需的，而不是必需的吗？请尝试将变量添加到父作用域。您可以使用Set变量并将作用域设置为1来执行此操作。非常感谢。现在可以了。您知道为什么脚本直接在服务器上运行时，这是必需的，而不是必需的吗？
