# Yanfly Engine Melody - Main Menu Melody
# Last Date Updated: 2010.06.13
# Level: Normal, Hard, Lunatic
#
# This script allows for menu item reordering along with importing in custom
# script scenes with ease so that there becomes little need to change the base
# menu script in order to add in a few items. This is a YEM version of the
# popular KGC Custom Menu Command. No credits will be taken on part of my own
# behalf for the work KGC did. All I merely did was use it to extend the
# capabilities of adding in common events, imported commands, and beefed up
# engine efficiency.
#
#===============================================================================
# Updates
# -----------------------------------------------------------------------------
# o 2010.06.13 - Bugfix regarding imported commands and common events.
# o 2010.05.15 - Conversion to Yanfly Engine Melody.
#===============================================================================
# Instructions
# -----------------------------------------------------------------------------
# To install this script, open up your script editor and copy/paste this script
# to an open slot below ? Materials but above ? Main. Considering the special
# nature of this script, it is highly recommended that you place this script
# above all non-core scripts. Remember to save.
#
# Scroll down and edit the module as you see fitting for your game.
#
# -----------------------------------------------------------------------------
# Debug Shortcuts - Only during $TEST and $BTEST mode
# -----------------------------------------------------------------------------
# During testplay mode, pressing F5 while the main menu is active will fill
# all party members' HP and MP to full.

So the problem line is "command = @command_window.method" Try SHIFT+CTRL+F and see if any other scripts use it... Unless Melody is your only script?

Are you just using the Melody Menu? Maybe it's possible you need Melody's Core Fixes and Upgrades for the Imperative Game Interpreter fix?

I think I might need that. . .where could I get it?

Like I said, it's incorporated in Yanfly Engine Melody Core Fixes and Upgrades. I remember seeing a link to the fix alone a long time ago but I can't remember wear... But you have Melody, so just grab that script and insert it.
