This is a hard one

I have tested this on the console and it works but I keep getting ht eerror "Bummer! Try again!" :(

Any help?

def add(num1, num2):
    return (float(num1) + float(num2))
    num1 = int(input("Give me a number: "))
    num2 = int(input("Give me another number: "))
except ValueError:
    return ("None") 
    add2 = add(num1, num2)

I see that you've worked on this a lot! You are sooooooo close. And it's not so much that your code is wrong, it's just that it's not doing what Treehouse wants. And the biggest thing here is that Treehouse is going to send in numbers to your code to test it. And you are promptly writing over what they're sending with your input prompts to the user. Also, in the exception you're returning the string "None" not the value None.

Take a look at just how close you really are:

def add(x,y):
        return float(x) + float(y)
    except ValueError:
        return None

Hope this helps! :dizzy:

Wohoo it worked! I think I understand how this thing works now. I cant add in any input prompts. Also I cant use none as a string.

Thanks Jennifer! :)
