The task specifically mentions that it wants you to add a pair of radio buttons to your form, each nested in its own label element. But in the code above, you have put your radio buttons outside of your form element. You need to put the radio buttons inside the form element.
One more thing I would like to mention is that, it’s considered best practice to have a for attribute on the label element, with a value that matches the value of the id attribute of the input element.
So, here you can use a for attribute for your Indoor button on its label element and have a value of “indoor” for that attribute which matches the value of the id attribute of the input element. Similarly, you can use a for attribute for your Outdoor button on its label element and have a value of “outdoor” for that attribute which matches the value of the id attribute of the input element.
