Theres a few things you need:
def add(x, y)::
try: a = float(x)
b = float(y) except ValueError: return None else:
return a + b

Your code is very close. First you need to indent the try, except and else statements so they are inside the function. Second, in your try statement you just need to remove the input statements and use the arguments passed into the function. Third, return statements don't use parentheses. Also, to pass the challenge you need to use the same two variables throughout.
def add(numb1, numb2): try: numb1 = float(numb1) numb2 = float(numb2) except ValueError: return None else: return numb1 + numb2
