Cannot go forward to next lesson

Tell us what’s happening:
Hi, I did well what the lesson asked, but the program says:
“Give your radio buttons the name attribute of indoor-outdoor.
Each of your two radio button elements should be nested in its own label element.”
I fulfilled all requirements, but the program does not accept.
Please fix it.

Your code so far

Hint: think over this statement.
nested means something that is inside a larger one.
