I have everything correct except for the part where a radio button has to be under a form label

Tell us what’s happening:

Your code so far

  <p>Click here to view more <a href="#">cat photos</a>.</p>
  <a href="#"><img src="https://bit.ly/fcc-relaxing-cat" 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 type="text" placeholder="cat photo URL" required>
    <button type="submit">Submit</button>
 <label> for="indoor"
   <input id="indoor" type="radio" name="indoor-outdoor">Indoor
  <label> for="outdoor"
    <input id="outdoor" type="radio" name="indoor-outdoor">Outdoor

Link to the challenge:

This is an attribute for the label tag.
Just add it inside label tag the way you normally add an attribute.
Does that help?

Yes thank you very much!

for="indoor" should be inside of <label /> tag

And secondly, the challenge wants you to put your radio buttons inside the <form></form>. Are they inside the form? They are not.

please close the label tag very well.
