Hi Zachary,

You are thinking to hard. It's not so complicated. In the first stage you should create this wile loop:

while counter < numbers.count {
 counter++
}

After that you should add the code required for the second challenge to the code you already have. Like this:

while counter < numbers.count {
 /*new part*/ sum = sum + numbers[counter]
 counter++
}

This works perfectly fine.

Hope this helped!

Kind regards, Jari
