I managed to figure it out. The instructions aren't perfect. After messing around for a bit I was able to figure it out. Following the instructions didn't work.
As for the parts. I think the person who did the ordering for my program has handled it. The screwdriver that is provided isn't that good either. Some of the screw heads haven't been manufactred properly and the screwdriver doesn't fit properly. Overall these kits have been a headache to use with the younger kids. I'm not sure I would order these again.
