Hi Virochaan,

you're close but:

1) the two float conversion checks need to be inside the try block

2) You don't need to call the function or print the result

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