i did not understand the second task

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

while counter < numbers.count{
print(numbers[counter])
counter += 1

}
```

Your solution is pretty close, and arguably you figured out the hardest part. The task can be divided into two parts:

The first is to figure out how to retrieve each value from the `numbers` array using the `counter` as the index. That you have actually done successfully with the `numbers[counter]` code.

The second is to add that value to the `sum` variable, that is the part you are not doing. Instead you print the value out, which is not what the task requested.

The instructions provide two examples of how you can add one value to another `sum = sum + newValue` or the shorthand `sum += newValue`. If you use that code instead of the print code you have currently like this:

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