I'd love to help you but damn I haven't done those in a year. I just remember that the line from B to A1 has to have a 1 and from B to A2 has to have an N. Also you should do a unity of A1 and A2 symbol that turns into a double line going to A. I think that's how it basically but I'm sure there's some oddities in there.
