Trouble with my existing input element being nested

I am trying to figure this part out but am stuck. I read the other forum solutions and tried that but I have been stumped on the same part for 40 minutes. Any help?

  **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://cdn.freecodecamp.org/curriculum/cat-photo-app/relaxing-cat.jpg" 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="https://freecatphotoapp.com/submit-cat-photo"><input type="text"></form>

</main>

Challenge: Create a Form Element

Link to the challenge:

The error says:

The existing input element should be nested within a form element.

That doesn’t look like the input element that it started with - it’s been changed.

This was the original input:

  <input type="text" placeholder="cat photo URL">

When I fix that, the code passes for me.
