Help I cant see to get passed this part

Tell us what’s happening:

I have no idea how to solve this issue.
Make your text input a required field, so that your user can’t submit the form without completing this field.

Then try to submit the form without inputting any text. See how your HTML5 form notifies you that the field is required?
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=""><input type="text" placeholder="cat photo URL">
<button type="submit">Submit</button></form>
<input type="text" required>

Challenge: Use HTML5 to Require a Field

Link to the challenge:

You don’t need to add your own input at the bottom. Remove this:

<input type="text" required>

Above the submit button, there is already a text input. This is the input you would make required.

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

Would be…

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

It worked! Thank you.
