Should Global Variables Retain Their Values After Program Execution

[SEzzell]

I was working on my first HP Prime program and can get the program to produce output with correct answers for values I am seeking, however, I desire to be able to continue using the values stored in the global variables I created when the program is run with the data I input. After running, the variables are listed as user variables for my program, but have not retained the values shown in the output statements. It appears the values are all zero. I have attached a text file with the code and would appreciate any help.
