add = (num1 + num2)
except ValueError:
return(None)

return(a + b)

Treehouse TeacherHi there! You're really close here. There's only one line that's incorrect and it's this one:
add = (num1 + num2)
You started by trying to see if the num1 and num2 could be converted to numbers and then assigned them to a and b, but then you never did anything with a and b. Also, this code would try to take the numbers passed in and add them without first converting them and then assign them to a variable named add, but that's what your function is named!
So if I switch out that line for this line:
return a + b
your code passes! Hope this helps!

As I said before, that line that creates the variable named "add" doesn't seem to be related to the challenge. If you eliminate that line completely you should pass the challenge (you don't need to replace it with anything).

Treehouse TeacherSteven Parker is correct, you can remove the line and not replace it and pass. My line that I posted will work, but also gives you the option to erase the
elseclause at the end.
