OK, hrm... well go into TOns of Addons 02 and look for this section of the script:
#::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::
# I suggest you don't edit anything below this line except for the
# configurations for the add-ons.
#::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::
attr_accessor :FPS_MODULATOR
attr_accessor :SPEED_MODULATOR
attr_accessor :DEATH_TOLL
attr_accessor :WINDOW_BATTLERESULT
attr_accessor :UNIQUE_SKILL_COMMANDS
attr_accessor :HEAL_AT_LVLUP
attr_accessor :HPSPPLUS
attr_accessor :TARGET_EM_ALL
attr_accessor :QUICK_PASSABILITY_TEST
attr_accessor :MINIMAP
attr_accessor :ENEMY_STATUS
attr_accessor :PASSIVE_SKILLS
attr_accessor :SKILL_SEPARATION
attr_accessor :MULTI_HIT
attr_accessor :EQUIPMENT_REQUIREMENT
attr_accessor :ITEM_REQUIREMENT
attr_accessor :HP_SP_CRUSH
attr_accessor :ROULETTE
attr_accessor :CHAIN_STATUS
attr_accessor :ACTOR_ITEMS
attr_accessor :HP_PERCENT_STATES
Add this line directly below attr_accessor :HP_PERCENT_STATES:
attr_accessor :MONSTER_AREAS
IE. it should look like this:
#::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::
# I suggest you don't edit anything below this line except for the
# configurations for the add-ons.
#::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::
