Thank you Alan and Kent.
Your suggestions caused me to completely start
from scratch. It also looks like the "nested sequence"
will be easier to use in the long run (and I'm into this
for the long run!). 8^D

This is working properly now on my
GNU/Linux system running Python 2.4.3:

#!/usr/bin/python

import random

# setup environment
#             N S E W U D T
travelTable=[[0,2,0,0,0,0,0],    # ROOM 1

travelTable[room-1][6] = -cnt
else:

cnt -= 1

# put positive numbers in the last element
# of two specific lists overwriting any
# number that exists
a = range(1,99)
travelTable[3][6]= 100 + random.choice(a)
travelTable[15][6]= 100 + random.choice(a)

"You assist an evil system most effectively by obeying its
orders and decrees. An evil system never deserves such
allegiance.  Allegiance to it means partaking of the evil.
A good person will resist an evil system with his or her
whole soul." [Mahatma Gandhi]
