我有5个单选按钮组。我希望用户只能在每个广播组中选择一个部分。我的第一组工作正常，只选择一个部分，但是当我选择某个部分而不是从1选择的所选按钮时，它选择另一个部分。
我的代码是：
<html>
<head>
<title> Checkboxes and radio buttons assignment 4 </title>
</head>
<body>
<form name=form1>
<h2>Complete the following</h2>
<hr>
Tick the box if you have the following:
<h2>History of Hereditary Disease </h2>
Heart <input type="checkbox" name=chkHeart value="Heart"> <br><br>
