Strange error on twoples.py

Hi! I feel my code is ok at least the function name is correct. But challenge showing an error message "couldn't find multiply". Anything helpful from you will be appreciated.

twoples.py
def multiply(*args):
    total = 1
    for num in nums:
        total = total * num
    return total

Yes, changing for num in nums: to for num in args also works!

Since you are expecting exactly one argument, using a leading * can mislead other programmers into thinking more than one argument is OK. It would better to use plain arg in this case.
