You're doing great! Just one more task but it's a bigger one. Right now, we turn everything into a float. That's great so long as we're getting numbers or numbers as a string. We should handle cases where we get a non-number, though. Add a try block before where you turn your arguments into floats. Then add an except to catch the possible ValueError. Inside the except block, return None. If you're following the structure from the videos, add an else: for your final return of the added floats
def add(x, y) try: a = float(x) b = float(y) except ValueError: return None else: return True

You aren't too far away from being correct. Please see the code I used to complete this challenge below:
def add(x, y): try: total = (float(x) + float(y)) except ValueError: return None else: return total
Hope this helps! Happy Coding!!!
