What's not right?

     <input type="radio" Indoor 
     <input type="text" name="catphotourl" placeholder="cat photo URL" required>

Well, so far the thing that isn’t right is that we have no context for this. :wink:

Please provide a link to the challenge so we know what you are trying to do.

Also, a quick observation is that the first input does not have a closing angle bracket.
