Question Class Menu Help

I'm trying to add help files to the class selection menu, using the code found here:  drive.google.com/drive/folders/0B40XbRH2...4C3QUNEZeOe2odDWOpfA

It's almost working, but no matter what I do, the STATE wants to stay in CON_QCLASS_HELP, and never allow me to actually pick a class.
Here's my code, can you see what I'm missing?

IF that is your code, you clearly have a mistake. Your case CON_QCLASS does not have a break statement so it falls right into the next case and it hits STATE(d) = CON_QCLASS_HELP

your case needs to define the next STATE(d) and then break before you hit the next case statement.
