Amended,

First note (I made the same error) your condition should be, counter is less than numbers. Not less than or equal to.

while counter < numbers.count

Next let's look at the value of numbers, it's an array. So you have to declare which item you're getting from the array.

sum = sum + numbers[counter]

Remember [counter] will define which item in the array the code is looking at.

Over all what you're aiming for is,

let numbers = [2,8,1,16,4,3,9]
var sum = 0
var counter = 0

// Enter your code below
while counter < numbers.count {
  sum = sum + numbers[counter]
  counter += 1
  }

If this answer helps please let me know.
