what is wrong with my while loop syntax

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

// Enter your code below while index < numbers.count { print(number.[index]) index++ }

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

// Enter your code below
while index < numbers.count {
  print(number.[index])
  index++
}

There's no need for the index variable as they set up counter to serve the same purpose. Also, they wanted you to sum up the numbers in the numbers array, not print them:

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