I remember that being the only thing that I really got hung up on. I don't remember exactly what the problem was, what I was doing wrong or how I corrected it, but when I figured it out I couldn't believe I spent so much time trying to figure it out. It went extremely smoothly after realizing what I was doing.
Sorry, I know this is an incredibly useless post but just know that once it "clicks" in your mind, you've got it. Maybe someone else with a better memory and a similar issue will chime in.
