It's actually in the first line where it says work back and forth on circular needle. It means the same thing. So when you get to the end of the row, turn your work just like you would a straight needle to begin knitting again. You will end up knitting with the other end of the circular needle.
For editing your post--if you look in the lower right hand corner of your post, there is a tiny button that says "edit". If you click on that, you should be able to edit your post to remove the pattern. If you are still having trouble, one of the mods should be able to help you out.
