It doesn't look like you've written any code yet. If you don't know how to start, you might want to watch the Loops video again. It contains an example that is very close to what you need to do for this challenge.

Thanks Steven for the help. I understand the loops and how they should look. What I'm struggling on is how I would specify the start int, and stopping at end int.

package loops

import "fmt"

func CountByThrees(start int, end int) {
  for i := start; i <= end; i+=3 {
  fm.Println(i)
  }
}

I know for i := start; i <= end; i+=3 { is definitely wrong. But maybe it will help guide where my mental struggle is :)

Your loop looks perfectly correct. :+1: The only error I see is on the next line where you have "fm" instead of "fmt".
