Hi there,

I think you need brackets around the while condition:

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

// Enter your code below

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

Also, you want to add the array together, not print out the values? That's the second part of the challenge, anyway!

I hope this helps.

Steve.
