It's nothing wrong with the logic of your code, however, the indentation missed the mark(remember, indentation is an important part of Python's syntax). Every line after the 1st line needs to be shifted 4 spaces to the right.

def add (one, two):
    try:
       total = float(one) + float(two)

    except ValueError:
        return None
    else:
        return total

Now it should pass.
