Question

This is supposed to add values that are odd and divisible by 7 to an array(which it does in playground) how come this is not working in the challenge?
var results: [Int] = []
for n in 1...100 {
    if n % 2 != 0 && n % 7 == 0 {
       results += [n]
    }
}
```operators.swift
var results: [Int] = []
for n in 1...100 {
    // Enter your code below
       if n % 2 != 0 && n % 7 == 0 {
       results += [n]
    }
    // End code 
}
```

The code checker can often be quite picky, it asks you to append the items to the array, you are concatenating them to the array. The result of those two actions are exactly the same, but the code is different. And the code checker is looking more at your code than your result for this challenge.
If you add to the array using the append method like this:
```Swift
var results: [Int] = []
for n in 1...100 {
    // Enter your code below
       if n % 2 != 0 && n % 7 == 0 {
       results.append(n) // Add to the array using append rather than concatenation
    }
    // End code 
}
```
Then your code will be accepted.
