You've set up your for loop just fine! However, the challenge doesn't ask you to print anything. They want you to take multiplier and multiply it by 6 then put that into the results array. So the end result array will contain 6, 12, 18, 24, 30, 36, 42, 48, 54, 60. Here's how I did it:

// Enter your code below
var results: [Int] = []
for multiplier in 1...10 {
  results.append(6 * multiplier)
}

They set up the results array for you. Your job is simply to take the result of 6 * multiplier and put it in the array. Hope this helps!
