英文:
How to combine multiple display conditions in Perl/HTML in a multiple choice survey
问题
我正在设计一个调查问卷，它是用HTML/CSS编写的，使用了Perl逻辑。
在开始处有一个筛选问题（q1），有三个答案：
- 一次车祸（broad_screen_1）
- 糖尿病诊断（broad_screen_2）
- 癌症诊断（broad_screen_3）
- 心脏病诊断（broad_screen_4）
- 以上都不是（broad_screen_5）
在代码中，答案被记录为（1='未选择'，2='已选择'）。这是多项选择。
我希望在调查问卷的屏幕外部分中，如果满足以下条件之一，则显示屏幕外部分：
- broad_screen_3未被选择（$broad_screen_3 !=2）
- broad_screen_5被选择（$broad_screen_5 = 2）
每个显示条件单独运行时都有效，但两个条件一起不起作用。我尝试添加OR作为布尔运算符，还尝试使用逗号分隔两个参数，但都没有成功。
提前感谢。
英文:
I am designing a survey and it is written in HTML/CSS and uses Perl logic.
I have a screening question (q1) at the start which has three answers:
A car crash (broad_screen_1)
A diagnosis of diabetes (broad_screen_2)
A diagnosis of cancer (broad_screen_3)
A diagnosis of heart disease (broad_screen_4)
None of the above (broad_screen_5)
In the code, the answer is recorded as (1='not selected', 2='selected'). It is multiple choice.
I would like a screen-out section of the survey to be displayed if:
broad_screen_3 is not selected ($broad_screen_3 !=2) or if broad_screen_5 is selected ($broad_screen_5 = 2).
Each display condition works, but not together. How do I combine the two? I have tried adding OR as boolean operators, also added commas separating the two arguments but this does not work.
Thanks in advance.

由于您允许多项选择，答案本身不是等于3的变量。根据您的代码，它可能是一个类似于[2,3]的列表，一个类似于{2:true, 3:true}的字典，或者一个用逗号连接的字符串，如"2,3"。因此，如果有多个答案，您无法验证答案3是否等于某人的答案。
解决方法是：您可以简单地检查给定的答案中是否包含3。我们可以提供“代码特定”的答案，但您没有提供代码本身。所以这就是它的哲学。 
英文:
Since you allow multiple choices, the answer itself is not a variable that equals to 3. Depending on your code it might be list like [2,3], a dictionary like {2:true, 3:true} or a string that is imploded with a comma like "2,3". So you cant verify whether the answer 3 equals to someone's answer if there is multiple.
The solution of it: You can simply check whether the 3 is in the given answer or not. We could provide mode 'code specific' answer but you did not provide the code itself. So this is the philosophy of it.
