All of your code is correct, the only problem is your indentation. In python you need to indent the code inside a function further than the declaration, like this: 

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

Thank you so much i need to remember that indentation is a main key in Python.
