使用 Javascript 将变量传递到购物车
此问题是此问题的扩展：
我正在尝试根据上一页制作一个会议注册页面，该页面使用 JavaScript 将变量（名称、电子邮件、价格）传递到我组织的过时购物车。我还使用 CSSTricks 的研讨会注册 (http://css-tricks.com/examples/SeminarRegTutorial /）
目前，我的继续付款按钮在第 298 行产生“元素未定义”错误（与未解决的上一个问题相同，链接在上面^）：
switch (document.Information.amount.value) {
任何帮助将不胜感激。我对此无计可施。这是页面：

This question is an extension of this one:
Calculate order price by date selection value
I'm trying to make a conference registration page based off the previous page, which passes the variables(name, email, price) to my organization's outdated shopping cart using javascript. I'm also using Seminar Registration by CSSTricks (http://css-tricks.com/examples/SeminarRegTutorial/)
Currently, my proceed to payment button produces an 'element is undefined' error on line 298(same thing on unresolved previous question, linked above^):
switch (document.Information.amount.value) {
Any help would be greatly appreciated. I'm at my wits end with this. Here is the page:
