Are we using the print function for this?

Totally stuck here.

loops.swift 
// Enter your code below
var results: [Int] = []
for multiplier in 1...10 {
     multiple = multiplier * 6

 }
results.append(multiple)

Hi again! No, there's no need for the print. Remember that thing I said about individual items? In this case, your multiplier is the individual item. The only difference is that it is going over a range. The range is your group. It will start at 1 and go to 10. You are absolutely correct that you need to use the append method here. Right now, though, you are trying to append something called multiple (which is an undeclared variable by the way) to the loop after it runs.

Through each iteration of the loop you should be appending the multiplier times 6 to the results array. This means that the append needs to happen inside the loop. You're almost there! I think you can get it with these hints, but let me know if you're still stuck! :sparkles:
