having some trouble figuring this one out? As far as which syntax to use to finish the block.

and compute the values.

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

// Enter your code below

while counter <= 7 {

      counter += 7 



 }

Hi Dean,

You're nearly there with that.

You don't want to hard-code the 7, use the count property of the array. So compare the value of counter to the property numbers.count using less than.

Inside the loop, use += to increment counter by 1.

Make sense?

Steve.
