how do I put two exits in a maze?

[IOEPsych]

I have designed a Vizard maze with an 'exit' that when you move into this area of the maze you hear a 'yipee' sound and the programme closes. I now need to be able to have the option to have two separate exits (so that the maze can be solved in two ways) but I cannot seem to do this as when I put another 'E' into my text file ('E' = END) then the programme opens but doesn't run properly. Any thoughts!???

This bit of my script looks like this:

def allTimers(event):

if (event == LOG_POSITION):
logPosition()
if (event == JOYSTICK_MOVE):
doMove()
if (event == CHECK_KEYBOARD):
checkKeyboard()
if (event == CHECK_END):
checkIfAtEnd()
if (event == STOP):
viz.quit()

def checkIfAtEnd():
''' Checks if the current position is in the end square of the maze.
'''
global endPos
pos = viz.MainView.getPosition()
euler = viz.MainView.getEuler()
lowEndX = endPos[0]*mazeExptParams.XSCALE
highEndX = (endPos[0]+1)*mazeExptParams.XSCALE
lowEndY = endPos[1]*mazeExptParams.YSCALE
highEndY = (endPos[1]+1)*mazeExptParams.YSCALE
x = pos[0]
y = pos[2]

if (x >= lowEndX and x <= highEndX) and (y >= lowEndY and y <= highEndY):
viz.playsound('yipee.wav')
viz.killtimer(CHECK_END)
viz.starttimer(STOP, 2)
