Hey there,

At the moment, your code is saying:

"While counter is less than 1, add 1 to the counter."

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

// Enter your code below
while counter < 1 {  // While counter is less than 1, add 1 to the counter.
    counter += 1 
}

What you want your code to say is:

"While counter is less than the length of of the numbers array, add 1 to the counter"

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

// Enter your code below
while counter < numbers.count { // While counter is less than the length of of the numbers array, add 1 to the counter
    counter += 1 
} 

Make sure that you compare it to the length of the numbers array.
