I already answered both your previous question (https://teamtreehouse.com/community/what-is-wrong-with-my-code-100) and your original question (https://teamtreehouse.com/community/hello-i-am-having-trouble-when-i-add-the-except-value-error).
But I'll repeat it here:
Each task of the challenge builds on the last.
In a multi-task challenge like this, each task builds on the work you did in the previous steps.
It looks like you are on task 3, but some of what you needed for tasks 1 and 2 is missing here.  Remember the challenge started out by building a function named add?  The other tasks modify how the function works, but everything should still be within that function.
Also remember than anything that belongs inside a function must be indented.

Hello George, 
The error I see is that you're passing arguments to the "try" and not defining the function, those arguments should go inside the function instead, like this:
python
def add(john, kelsey):
    try:
        total = float(john) + float(kelsey)
    except ValueError:
        return None
    else:
        return total

Hope this helps :)
