Hello,

The challenge wants you to continue the loop until it matches the total number of values inside the array. So if the array has 5 values in it, the loop should go for about 5 times. So we need to get the amount from the array and compare it to a value that keeps our count.

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

// Enter your code below

while counter < numbers.count {
counter += 1
}

This says: while the counter is less than the number of values inside the array, then continue and add to the counter.

Hope this helps, good luck.
