I feel like i know the code needed for this just need a push in the right direction. what should i be defining in integars first, the numbers 1...10? then creating a new line for the actual loop with the constant?

var results: [Int] = [1...10]

You're correct that we're looping over the range 1...10. However, you tried doing this in the wrong place. As we go through the loop we're going to append a multiple of 6 into the results array. So this means you aren't going to add anything inside the array directly in your code like you tried. This gave you an error.

Below is the solution to the first part of the challenge to get you started. Let me know if you need help with the next parts!

var results: [Int] = []
let multiplier = 6;
for i in 1...10 {
  // code for challenge two
}

i found a different way in another comment that resolved it too! Thanks for such a quick response!! so in this case were actually defining the constant out of the function. didnt learn it that way in the videos yet, but makes sense why i was missing that one :)

The beauty is there are almost always more than one way to solve something! Maybe what you saw was this:

for multiplier in 1...10 {

}

This is actually what the challenge is looking for. So this would complete the challenge but makes less sense to me since this seems like it's saying the multiplier is 1, 2, 3 etc where I think of the multiplier as 6. Maybe I feel this way because they made us use the constant named multiplier.
