Help Please.

Hi I was wondering if anyone knows what I am doing wrong Thanks/Users/Zak/Desktop/Screen Shot 2016-06-21 at 5.12.53 PM.png

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

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

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

You have no idea how close you are! The bottom loop that you wrote is correct except that it has an extra period between the array name and the braces containing the index. Take a look>

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

Happy coding! :sparkles:

Odd. If I take the following code and paste it in the challenge it passes both steps.

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++  
}

Make sure you're removing everything and then copy/pasting this in there. If it continues to fail, you might need to contact support.

Yeah thanks I just messaged them. There might be some sort of connection thing. Thanks anyway.
