问题描述
我似乎找不到该代码的哪一部分是错误的.选择提交"按钮后，浏览器应显示日期，否.项，累计的总金额和其他详细信息，但在表单中显示其余的代码.谁能帮我吗?
I can''t seem to find which part of this code is wrong. After selecting "submit" button the browser should display the date, no. of items, total amount accumulated and other details but instead along the form it displays the rest of the code. Can anyone help me?
