Hi,

I think you've overthought this one, it asks you to try to turn them into floats, it if fails(except), return None, otherwise if it doesn't fail(else) return them both added together.

def add(x,y):

try:
    x = float(x)
    y = float(y)
except ValueError:
    return None

else:

    return x+y
