What does it mean "directly to the right of your radio button"?

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

Link to the challenge:

<someSelfClosingElement...>TextHereIsDirectlyToTheRightOfElement

You have indoor before the closing. You should put it after.

I actually figured it out a few minutes after this, but thanks anyways!
