  }

Nicholas, you are getting that error because multiplier exists only inside the loop. It's "out of scope" afterwards.

You need to append the value of the multiplication to the results array each time through the loop, like this:

var results: [Int] = []
let multiplier = 6
for n in 1...10 {
  results.append(multiplier * n)
}
