don't know how to retrieve the value from the array and add it to the sum.. my newValue statement is definitely wrong ha

In the body of your while loop you have the line that reads

(numbers[counter])

what purpose do you believe it serves?

to retrieve the values from the numbers array and go up by 1 index each time???

Close! In order to retrieve it, you would be needing to store it in a variable though (maybe the variable 'sum'? :) ). Try adding that to sum.

sum += numbers[counter]

still doing something wrong.. Sorry for being so bad haha. Here is the new code :

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

while counter < numbers.count { (numbers[counter]) counter++ }

sum += numbers[counter]

var newValue = counter + numbers

sum = sum + newValue

We all started somewhere! Those last 2 lines can go because they are not needed in the calculation.

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

while counter < numbers.count { 
    /* (numbers[counter]) this is what you originally had.
 All you needed to do was add that to sum each time you went through the loop*/
   sum += numbers[counter]
    counter++ 
}

/* sum += numbers[counter]  
this line goes inside of the body of your while loop.
It needs to be after the first bracket '{' but before the 'counter++'. 
Because you are using counter as an index,
you don't want to increment it before you can grab the value from the array. */ 

// var newValue = counter + numbers

// sum = sum + newValue
