it looks like it doesn't see the results array to append the multiplier to as an array.

the syntax is someArray.append(ints) ??

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

Justin, unfortunately you can't use results as both the name of the array and the loop variable. Try this instead:

for num in 1...10 {
  let multiplier = num * 6
  results.append(multiplier)
}

Gah thank you I wasn't thinking clearly about that being the name for the loop variable itself.

Justin, don't want to nag, but not a good idea naming num * 6 multiplier when 6 is really the multiplier. Suggest you do something like this instead:

for num in 1...10 {
  let multiplier =  6
  results.append(num * multiplier)
}
