Stuck on Value Error Challenge Task

Having trouble figuring out exactly what is wrong with this code. I tested by running integers through the function in the console (using print instead of return) and that printed the answer, floated. So I believe the problem is with

except ValueError:
    return("None")

When I would run a letter in the function the console would return:

Traceback (most recent call last):
  File "test.py", line 9, in <module>
    add(n, 5)

Thanks, Gary

trial.py 
def add(num1, num2):
    try:
        (float(num1) + float(num2))
    except ValueError:
        return("None")
    else:
        return(float(num1) + float(num2))

You are returning the string "None" instead of the object None

Remove the quotation marks from around None. The parens in the return statements are unnecessary.
