Looks like you've gone a little outside of the loop.

Remember the [counter] will tell the code which item from the numbers array you're after. I can't remember the exact term, but maybe stop back in on arrays just to reaffirm that knowledge.

Heres the code you're looking for.

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

// Enter your code below
while counter < numbers.count {
   sum += numbers[counter]
   counter += 1
}
