# Having trouble understanding when it tells me to set a condition that will eventually terminate please help thank you!

Swift 2.0 Collections and Control flow

This one might be a bit tricky so let's take it in steps. We have an array of numbers, nothing tricky, you've seen this before. What we want is to compute the sum of the numbers in the array. To do this we're going to use a while loop.

We have a variable ,sum, that will store the value of the sum of numbers from the array.

We also have a variable ,counter, which we will use to track the number of iterations of the while loop.

Step 1: Create a while loop. The while loop should continue as long as the value of counter is less than the number of items in the array. (Hint: You can get that number by using the count property)

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

var list = 0

while list < number.count
{
print(number[list])
list++
}
```

Hi Derrick,

You are making your answer to complicated. At first, you don't need the print statement, and second you can just use the counter property instead of making a new one called list. Your code can look something like this:

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

while counter < numbers.count
{
counter++
}
```

Hope this helped!

Hey Jari thanks for the reply but I'm still seeing this when I try entering your suggestion.."Ensure that you provide the while loop with a condition that eventually terminates"..any ideas?

I accidentally put number.count instead of numbers.count, if you change that it should work!

Sorry!

Regards, Jari

Ah I should've seen that too thanks again really appreciate it!
