Hello, I think my problem is very simple but I cannot figure it out. I am trying to add the even indices of the list <digits> into the variable <even>. The error persists on the last line of the function <oddEvenSame>. I do not understand why you cannot iterate through the list with the for loop to add the indices?

```
def main():
# Get Input Number
n = int(input("Enter a number:"))
# Call <oddEvenSame()>
oddEvenSame(n)
def oddEvenSame(n):
# Split all digits of <n> into their own index within <digits>
digits = [int(i) for i in str(n)]
# Add even indices of <digits> into <even>
even = 0
for j in range(0, len(digits), 2):
even += digits[j]
# Call <main()>
main()
```
