Whats going on?
For some odd reason, I keep getting the same error, over, and over, and over again.
Code:
numbers = [5, 6, 7, 8]
print "Adding the numbers at indices 0 and 2..."
print numbers[0] + numbers[2]
print "Adding the numbers at indices 1 and 3..."
print numbers[3]
And then it changes:
numbers = [5, 6, 7, 8]
print "Adding the numbers at indices 0 and 2..."
print numbers[0] + numbers[2]
print "Adding the numbers at indices 1 and 3..."
print numbers[2]
But I get the same error. Which is:
Oops, try again. Remember: the second item will have an index of 1. Make sure to access the second item by its index!
Or other codes:

numbers = [5, 6. 7, 8]
print "Adding the numbers at indices 0 and 2..."
print numbers[0] + numbers[2]
print "Adding the numbers at indices 1 and 3..."
print numbers[1]
Thanks.
