Hey,
What exactly is not working, or can you not figure out?
If you hover over any options that you're unsure of in the GUI, a tool tip will show which describes the option in more detail. Also, if you experience the script stopping unexpectedly, you can open the console logger and see if anything has been output - when the script stops of its own accord, it will always let you know the reason! (e.g run out of ammo, out of food, etc..)
