Tuples Packing Code Challenge

I'm getting an error that says "couldn't multiply valid values together," but when I copy/paste my code into IDLE and run it there, it seems to work. I don't know what the problem is. . .

twoples.py 
def multiply(*args):
    to_multiply = []
    for x in args:
        to_multiply.append(x)
    product = to_multiply[0]
    count = 1
    while count <= len(to_multiply):
        product = product * count
        count += 1
    return product

Did you really intend to multiply the product by the count?

I'm guessing you would rather multiply by one of the values you put into your to_multiply array.

Also check your loop to make sure you're running the correct number of times.

Now just a suggestion (it's not necessary to pass the challenge), you could multiply at the same time as you unpack so you would only need one loop (and no local array).

Hi guys, my Python level it's "I'm trying to understand what to change here after Steven's suggestions." Could you give me more hints ? Thanks.

Jennifer's approach is rather unique, as are my suggestions to her. Your own solution is most likely to be quite different and you will probably not encounter the same issues.

Thank you, I solved it and it was very much easier than I thought. I 'll try with slices as well.
