How to save variables after quitting and reopening in AppleScript? - variables

Question

I am writing a very complicated AppleScript application that requires variables to be saved after quitting. So if I set the variable while it is running, close it, reopen it the variable will still be the same.
This script is intended to bring up a setup menu on first run. Then save the preferences for after the application is closed. More Technical explanation:
When it starts (on run) it will check if isSetup is false if it is it will go to the function setup(). The setup() function sets preferences and sets isSetup to true. When I quit and reopen the application is runs the setup() function again.
I know I am not supposed to copy and paste full scripts but I can't find the replicate the error without it. Here it is:

Update: doesn't work
YES!!!! I finally found the answer. You have to remove the property aStatusItem : missing value from the stop of the script. This will prevent aStatusItem from being used between functions. Because of this the menu bar won't be removed when you press quit. To fix that problem at the end change current application's NSStatusBar's systemStatusBar()'s removeStatusItem:aStatusItem to tell me to quit. This quits the application resulting in the menu bar item being removed.
