I dont understand why it won't let me append the multiplier to results.

multiplier is coming up as "unidentified"

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

for multiplier in 1...10 {
  print ("\(multiplier) times 6 is equal to \(multiplier * 6)")
  }

  results.append(multiplier)

they didnt want you to print in the loop, just append it like this

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