Cannot compile/Append the array

I am having difficulty trying to append the array. The first part of the challenge I can figure out, but I am not sure on two things. How am I telling it "Pull 1-10 as the range to multiply by". When I insert numbers in to the array it doesn't seem to like that. Anyone have any input or a proper solution so I can see how it is done?

var results: [Int] = []

for multiplier in results {

Hey Justin Cruz,

You're almost there! Just one thing to clear up. You can't iterate over the results array in your for loop because it is empty. Instead of results, this is where you put the range you were curious about. Take a look at my code below:

var results: [Int] = []

/* This for loop takes the range of 1...10
Then for each iteration of the loop, it
assigns a number 1 through 10 to
the temporary constant multiplier. */

/* Each time the loop completes, it will
get the next number in the range and
update multiplier */

/* So the first time the loop runs:
multiplier = 1
The next time
multiplier = 2
The next time
multiplier = 3
All the way until the range is complete (10) */

for multiplier in 1...10 {
    /* this will add the value of multiplier * 6,
    to the results array, then start the loop again */

Hope this helps! Good Luck!

UGHGHGHGH!! No wonder I wasn't getting it! I kept wondering "Where the hell is it going to pull the sequence from". Thanks for the assist Steven.
