You've got this!!
You know you need to use a while loop and keep looping until counter is about to reach the same value as numbers.count. Perfect.
Inside the loop you need to increment counter else we'll be here forever! Again, you know to do that; counter += 1.
The thing you've not got quite right is adding the values of each of the numbersarray into sum. You want to access the value held in the array at the position in the array determined by counter so, like numbers[counter]. You don't want to print anything so leave that method alone.
Add that value into sum. Something like sum += numbers[counter] <- does that make sense to you? We're adding the value held at the counter position inside the numbers array into the cumulative value being gathered in sum.
The finished code looks like:
while counter < numbers.count{
sum += numbers[counter]
counter += 1
}
I hope that helps. Shout if not.
Steve.
