Can someone can help me figured this out please.

I don't understand my mistake.

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

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

Hi there! You're doing great, but you've got it just a bit backwards here. You're trying to get the item at the index of numbers from the counter array. But you should be trying to get the item at the index of counter from the numbers array.

numbers[counter]

Hope this helps! :sparkles:
