表格验证（重新审核） [英] Form Validation (revisited)
问题描述
感谢Yang（这是你的名字吗？）和Andy的建议。
我99％的路在那里，但现在无法得到重置按钮工作。
我已经包含了我的整个代码，并且如果有人
可以解释我哪里出错了，我将不胜感激。
TIA
Roger

Thank you to Yang (Is that your first name?) and Andy for your suggestions.
I am 99% of the way there but now cannot get the "Reset" button to work.
I have included the whole of my code and would appreciate it if someone
could explain where I am going wrong.
TIA
