The instructions clearly are incorrect. In step one, directions show inserting a metal rod along the long edge in both 'A' pieces. However, after the box is put together and it's ready to have the top put on with three hinges along the long side to connect to part 'A', that rod is keeping the hinges from being attached. So one must carefully dismantle the box to take the rod out, put it back together, and then attached the hinges. Not a good plan!
