Needing help with Step 45 pls

Okay so, it’s saying that I need to add an id attribute to the value of the radio button. I took a gander at the MWD page that talks about the id attribute and how to apply it. But, it explains it in a more basic way than what I’m given. Is the id attribute suppose to literally be next to Indoor? In which is the value of the radio button?

      <label><input type="radio">Indoor</label>
  <label><input id="indoor" type="radio">Indoor</label>
