I can't seem to pass challenge task 3 of 3:

def add(n1,n2): try: return float(n1) + float (n2) except ValueError: return ("None") else: return float(n1) + float (n2)

Thx

trial.py 
def add(n1,n2):
try:
  return float(n1) + float (n2)
except ValueError:
  return ("None")
else:
  return float(n1) + float (n2)

You don't need quotes around None

In fact, you don't need the else statement in this case, either, although that'll work just fine anyway. You'll either return None or the sum of the input values.

Thank you Gavin

In addition to your answer the other issue was the indentation in the try block. I did not have the whole try block indented.

Ah yeah, I saw the indentation but thought maybe that was a cut-and-paste problem. Good to see you caught that :)
