Challenge: Learn HTML by Building a Cat Photo App - Step 48

Link to the challenge:

Hello. What this step is asking of you, is that you assign a value to your radio buttons. This is because, as the hint says, without a value assigned to them, once the form is submitted (assuming either one of the buttons has been clicked) the data received will show indoor-outdoor=on, which is not useful since it doesn’t say whether the #indoor button or the #outdoor button was chosen.

To fix this, the step asks you to set the value attribute of each radio button equal to its id, so indoor for #indoor, and outdoor for #outdoor.
