Hey Ray,

You are on the right track, but there are just a couple of issues here.

  • First, you can't hard code a integer into the results array. You need this array to be empty so that when the results come back in the for loop, it is appended into an empty array. By putting the "6" into the opening declaration, the results will be appended after the 6, and thus, the array now includes another number.

  • Second, inside the for loop you have declared a constant that is not needed. You will do the math 6 * multiplier inside the append method.

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

I hope this makes sense and helps to clarify for you. Keep Coding! :)
