Mo, good start, but when you convert them to floats you need to save the results either by assigning the results to new variables, or back to the same variables. The challenge requires the latter:

def add(num1, num2):
  try:
    num1 = float(num1)
    num2 = float(num2)
  except ValueError:
    return None
  else:
    return num1 + num2

Since you are adding, I changed the names to num1 and num2.
