【问题描述】：
我创建了一个表格，用于跟踪在特定日期注册计算机实验室的学生人数。我的问题是当个人开始注册并且学生人数超过可用计算机数量时，我希望表单生成一条消息，无论是个人还是与该特定日期已经注册的人数相结合.
如果没有填满，我还希望它告诉他们实验室中还剩下多少个位置。
我的问题是，当太多人注册实验室时，我想知道我会添加什么代码来创建消息。我不知道从哪里开始或如何去做
现在我所做的只是跟踪注册人数。

您的问题是什么？您能否分享您已经拥有的代码，显示您实现上述要求的探针？
-
我已经在上面添加了我的代码并试图澄清我的问题......
-
您在执行此任务时遇到的具体问题或困难是什么？您是否尝试过无法正常工作的东西？
-
我不知道如何才能让这种类型的验证正确编码并且找不到代码资源。从那以后，我实际上重新编码了页面并更新了上面的源代码......我想知道如何将验证编码到不允许我安排超过 20 台计算机的表单中。
