Hi Brendan. Task 2 wants us to retrieve every value from the array after it has been accounted for, so that it can add to the sum. In order to do this, we must call the array & use the "counter as an index value," adding that value to the sum. We can do it like this:

while counter < numbers.count { sum += numbers[counter] counter += 1 }

Hope this helped. :)
