what is the wrong here

// Enter your code below var results: [Int] = [] for multiplier in 1...10{

results[multiplier-1] = (multiplier * 6) }

loops.swift 
// Enter your code below
var results: [Int] = []
for multiplier in 1...10{

results[multiplier-1] = (multiplier * 6)
}

Close!

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

You need to create the multiplier variable outside the loop and give it a value, and then use it in the loop. You also need a loop counter (the i in the code above).

I think your code might actually work. But it's not what they're looking for. They want you to use the .append function. Try this out: 

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

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

Jennifer's right, the code works, but not in the challenge. The editor won't accept it. I tried. When it says 

define a constant that temporarily stores the value in the iteration process. For the loop you're writing, name this constant multiplier"

you won't get past Task 1 unless there's a multiplier declared. It's interesting, but I just noticed that in the code I sent you multiplier is a var not a let, so the editor should have rejected my code as well!
