Need help with radio buttons

cant seem to get this radio button figured out. i dont know what im doing wrong ive tried in 3 different ways and watched the videos and its still not working. what am i doing wrong?

Your code so far

  <p>Click here to view more <a href="#">cat photos</a>.</p>
  <a href="#"><img src="" alt="A cute orange cat lying on its back."></a>
  <p>Things cats love:</p>
    <li>cat nip</li>
    <li>laser pointers</li>
  <p>Top 3 things cats hate:</p>
    <li>flea treatment</li>
    <li>other cats</li>
  <form action="/submit-cat-photo">
  *<input for="indoor" type="radio" name="indoor-outdoor">*
*  <label for="indoor"Indoor</label>*

    <input type="text" placeholder="cat photo URL" required>
    <button type="submit">Submit</button>

you have not nested the input element inside the label element
you need to put the input between the tags of the label element
