You didn't format your question, but this is the answer to the challenge

def add(x, y):
    try:
        return float(x) + float(y)
    except ValueError:
        return None

Weren't we supposed to use an else as well?

def add(num1, num2): try: a = float(num1) b = float(num2) except ValueError: return None else: return(a + b)
