Answer 1

您缺少右引号：

document.write("<br> Your second Entry: "+secondInt+"<br>);

Answer 2

You are missing a quotes here: 您在这里缺少引号：

 document.write("<br> Your second Entry: "+secondInt+"<br>);

Should be: 应该：

 document.write("<br> Your second Entry: "+secondInt+"<br>");

Hope this helps. 希望这可以帮助。

Answer 3

您应该关闭双引号脚本的第四行。

document.write("<br> Your second Entry: "+secondInt+"<br>");
