17,232 PointsThe challenge doesnt tell you to print the result, it tells you to store the result in the "sum" variable. In the body of the while loop you need to do the calculation and that needs to happen before the count update. To keep track of witch values in the array to calculate you use the counter value, since that value will change for every iteration the loop goes through you can simply add sum to numbers[counter] and update sum to that result.
{
sum = sum + numbers[counter]
counter += 1
}
