working with loops recaping on challenge part 2 retrieving from inside the array

Question

2 different people have the the same problem but got help where it was not the main or what I needed.
```loops.swift
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
}
```

It looks like your loop is slightly off.
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
swift
while counter < 7 {
    counter += 1
    var newValue = numbers[index]
sum += newValue
}

to this
swift
while counter < 7 {
    sum += numbers[counter]
    counter += 1
}

This lets you step through your array, add up the numbers, and increment your counter.
