Hi Michele,

the add() function should work for all float number arguments that you pass in, so make sure that you don't use fixed numbers. You can name these arguments a and b, for example (or float1, float2, but the names should match within the function). Using a = float(a) you can convert the passed in argument a to a float number (the same for b). If this conversion is not possible, it means that a and/or b are not float numbers (so, it checks if a and b are float numbers). You don't need to call the function at the end.

def add(a , b):
    a = float(a)
    b = float(b)
    return a + b
