Can't figure this out.

"Inside the body of the loop, we're going to use the multiplier to get the multiple of 6. For example, if the multiplier is 1, then the multiple is 1 times 6, which is equal to 6.

Once you have a value, append it to the results array. This way once the for loop has iterated over the entire range, the array will contain the first 10 multiples of 6."

Hey Ryan Minnick,

You're almost there!! What you need to do now is use the append() method to add the result of multiplier * 6 to the results array.

for multiplier in 1...10 {

results.append(multiplier * 6)
// you take what you want it to append to, in this case the array results
// you use the append method, append() to say "hey I want to add what's in these parentheses"
// then in the parentheses you put what you want to add, which is the multiplier times 6

Next time you can easily post your code in your question and use the Markdown Cheatsheet (above the post button) to format it.

Good Luck!
