title: Why isnt this HTML Form valid?
body: <p>Hi recently i started a course, Ive been able to troubleshoot all my other validation errors, but i cant see why this wont validate with w3?</p>
  
  <pre><code>&lt;div id="conform"&gt;
  &lt;form method="post" action="" id="form1"&gt;
   Name:  &lt;input type="text" name="first_name" /&gt;&lt;br&gt;&lt;/br&gt;
  Subject: &lt;input type="text" name="department" id="department"/&gt;&lt;br&gt;&lt;/br&gt;
      Department:
       Sales  &lt;input type="radio" name="red" id="red"/&gt;
       Support    &lt;input type="radio" name="amber" id="amber"/&gt;
       Other  &lt;input type="radio" name="red" id="green"/&gt;&lt;br&gt;&lt;/br&gt;
       Content:   &lt;textarea name="details" id="messagedetails" cols="30"&gt;
       &lt;/textarea&gt;&lt;br&gt;&lt;/br&gt;
       &lt;input type="submit"  value="Submit"/&gt;
  &lt;/form&gt;
  &lt;/div&gt;
  </code></pre>
