1. When doing radio selection, I set up two items with a total of 4 options. I planned to have one option for each of the two items, but the entire page can only be selected for radio. What's going on? I used it wrong. Have you typed it, or is there something missing?

2. The relevant code is as follows:
{% extends 'base.html' %}

{% block body %}

<h2>{{ the_title }}</h2>

<form method='POST' action='/search4'>

<p>Fill in the information and click this button to start matching:</p>
<p><input value='Start matching! ' type='SUBMIT'></p>
</form>

{% endblock %}

3. There is one option for each of the two items in this plan, but only one option can be selected on the entire page.
