functions and exceptions

can't seem to pass the challenge without getting that Task 1 is on longer passing. I tried the code in workspace and it works, wondering what i missed from the challenge objective.

trial.py 
def add(e,r):
    try: 
        e= 3
        r= 4
    except VlaueError:
        return None 
    else:
        return float(e)+float(r)

You spelt ValueError incorrectly.

thanks, must have been a typo but I'm still getting the same output of "Task 1 no longer passing"

It took me about 20 minutes to get this down, but I finally got it:

Your "try" block doesn't actually have a code to test, it just has the integers for the arguments. The code I used for try was: add=float(x)+float(y)

The "None" in your except block needs to be in parenthesis, such as: return (None)

And the remainder of your function (minus the "add(3, 4)" that should have been present in all three challenges) should be under the "else" block (indented of course): else: e=float(e) r=float(r) return(e+r)

add(3, 4)

I hope this helps!
