Really stuck!

Hey guys,

I'm at a loss at why I'm unable to get past the second stage of this challenge?

Would be really helpful if anyone could shed some light!

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

// Enter your code below

while counter < 6 {
    numbers.count
    counter++
}

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

If you haven't got it already, just omit your first while loop, your second one is correct

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++
}
