Problem with "form" element

Tell us what’s happening:
Hello, I am currently having problem with the elements,
The website says my “action” is not settled, and I do not know the reason why.
Does someone know where is the problem? Thank you
My “form” coding lines:

 <form action="/sumbit-cat-photo">
  <input type="text" placeholder="cat photo URL">
  </form>

**Your code so far**
<h2>CatPhotoApp</h2>
<main>
  <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>
  <ul>
    <li>cat nip</li>
    <li>laser pointers</li>
    <li>lasagna</li>
  </ul>
  <p>Top 3 things cats hate:</p>
  <ol>
    <li>flea treatment</li>
    <li>thunder</li>
    <li>other cats</li>
  </ol>
  <form action="/sumbit-cat-photo">
  <input type="text" placeholder="cat photo URL">
  </form>
</main>
