Hey there Carlos,

you were on the right track but the problem is that you have to append the result of multiplier * 6 to the results array inside of the loop. So just write the statement you have in your loop right now as an argument in the append method on the results array and it should work!

Also note that if you append multiplier to the results array outside of the loop it won't work because the multiplier doesn't exist outside of the loop.

This is a working example:

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

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

I hope that helps, good luck! :)
