2 different people have the the same problem but got help where it was not the main or what I needed.
let numbers = [2,8,1,16,4,3,9]
var sum = 0
var counter = 0
// Enter your code
while counter < 7 {
counter += 1
var newValue = numbers[index]
sum += newValue
}

The problem is that you don't have a variable for index declared either inside or outside of your loop.
Honestly, you don't even need a separate index variable. You can use your counter instead and save yourself some extra work.
Change what you have here
while counter < 7 {
counter += 1
var newValue = numbers[index]
sum += newValue
}
to this
while counter < 7 {
sum += numbers[counter]
counter += 1
}
This lets you step through your array, add up the numbers, and increment your counter.
