Thanks guys for the replies.
I have implemented the declaration and initialization in the User Variables section of Config.dat (Both INT's initialized to a value of 2).
Pre Reboot my two variables are:
Var_A (value is 4)
Var_B (value is 7)
After reboot
Var_A (value is 2)
Var_B (value is 2)
Maybe I am still doing something wrong as what I would like to happen is after reboot my variables are still:
Var_A (value is 4)
Var_B (value is 7)
Thanks
