``` Hey Ricardo Gonzalez,

You're on the right track. You have the append part correct, we just have to look at the the conditions you are evaluating for. You need to check if each case of n is true for two conditions. These are if n is odd and if n is a multiple of 7.

To check if n is an odd number, we can use the remainder operator and 2. If the result is not equal to 0, this mean the number is not even because it did not divide by 2 with no remainder. We then use the AND operator to check if this number satisfies the condition where n is a multiple of 7.

To check if n is a multiple of 7, we do something very similar to checking if n is odd. Here we will use the remainder operator but this time with 7. We will check if the result is equal to zero. If it is, this means that the number was successfully divided by 7 without a remainder and that the number must also be a multiple of 7.

```var results: [Int] = []

for n in 1...100 {
