While Loops 2 of 2 Challenge

Have exhausted all possibilities with this challenge; including those suggested in the community and not getting through the challenge...All works fine in my playground! Here is my answer:

while counter < numbers.count {
    sum += numbers[counter]
    counter++
}

Help!

Challenge: Using the value of counter as an index value, retrieve each value from the array and add it to the value of sum.

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

Part 1: while counter < numbers.count { print (numbers[counter]);counter++ }

Hello Rosana:

I am not sure 100% what is going on with your code, or what you are missing. But it looks Ok to me, I went to the challenge and did it myself to compare it to yours.

Here is my code

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++
}

This passes just fine. Perhaps you deleted something by accident ? give it another try see if it works.

"Make sure your condition allows for iteration over all elements in the numbers array and check your calculation of sum!"

I have no clue what is going on.. It could be the compiler. Have you tried closing your browser and trying it again ?
