Step 48 doesn't accept my code

Given the code i’ve provided, the radio buttons for “Indoor” and “Outdoor” seem to be correctly placed inside their respective label elements so why does it not accept my code?

If you have a question about a specific challenge as it relates to your written code for that challenge and need some help, click the Ask for Help button located on the challenge (it looks like a question mark). This button only appears if you have tried to submit an answer at least three times.

The Ask for Help button will create a new topic with all code you have written and include a link to the challenge also. You will still be able to ask any questions in the post before submitting it to the forum.

Thank you.
