Good job on the for loop, but a few other things that did not match what the challenge wanted. See your modified code below with comments inline.

// Enter your code below
var results: [Int] = []

let multiplier = 6  // We declare the multiplier tha twe will use in the for loop.

for number in 1...10 {  // We are using number as our iterator variable.
    results.append(number * multiplier)  // We are not printing the result but appending it to the array.
}

Thanks so much Nathan! I saw your post somewhere else after I posted this question and I didn't understand why our code was so different (obviously yours was the right one)

Thank you so much for the detailed explanation.

Yeah, it's a tough one. As you can see we all have a problem with it! That's what makes these challenges so great! They really ensure that you understand what you are learning before you can move on. :)

Keep up the great work!!! :D
