RPG Maker VX Ace Script Error

#------------------------------------------------------------------------------#
#  Galv's Character Animations
#  Edit by KK20, Chaucher and Ally for Fleshforward
#------------------------------------------------------------------------------#
# KK20's Notes:
#   The script has been modified to allow map events to have the various
#   animations like the Player and Followers did in the original script.
#
#   For an event to have idle and move sprites, simply put the following:
#          [idle]
#   anywhere in the event's name.
#------------------------------------------------------------------------------#
#  For: RPGMAKER VX ACE
#  Version 2.0
#------------------------------------------------------------------------------#
#  2013-01-07 - Version 1.7 - Slight tweaks
#  2012-10-06 - Version 1.6 - Updated alias names for compatibility
#  2012-10-06 - Version 1.5 - Added dash speed option. Fixed some code
#  2012-09-21 - Version 1.4 - Optimised the code significantly (to my ability)
#                           - Some bug fixes
#  2012-09-21 - Version 1.3 - Added ability to repeat common event
#                           - Added follower animations
#  2012-09-20 - Version 1.2 - fixed compatibility with Galv's Region Effects
#  2012-09-20 - Version 1.1 - added idle common event, removed unnecessary code
#  2012-09-20 - Version 1.0 - release
#------------------------------------------------------------------------------#
#  Designed to give actors additional animations such as:
#  - Idle
#  - Walking
#  - Dashing
#  - Custom (run a common event if you've been idle for a period of time)
#
#  INSTRUCTIONS:
#  1. Copy this script below materials and above main
#  2. Create your charsets to use one characterset per actor. (This is where
#     version 2 differs from version 1 greatly.
#     The first character in the charset is the Idle animation
#     The second character in the charset is the Walk animation
#     The third character in the charset is the Dash animation
#
#  (See demo if you don't understand) This change was done to reduce processing
#  significantly and prevent lag when doing too much at once)
#
#------------------------------------------------------------------------------#
#  KNOWN ISSUES:
#  - Move Route Change graphic commands only work when the switch is on.
#    Then if you turn it off again, the graphic changes back to the original.
#    Use "Set Actor Graphic" event command to change instead.
