Okay I got this part resolved but when I run the program it prints out
the initial value 150.  I then change the value to 100 and print it out
and it shows me 100.  If I then go look at the list or run the program
again I find that my initial value is still there.  I've tried this
while logged onto the web based page and when I'm not logged in and I
get the same results.  The program is exactly as it is above.
