help finishing this program
the program is a 2d floor plan navigating program which displays which room you are currently in, a description of the room and available exits for n, e, s, w directions.
the program runs okay until you hit a direction (n, e, s, w key) and press enter.
any idea why its not working 100%?
help is greatly appreciated guys thanks in advance
