Working on GUIs, and Need HELP!

[JayRay]

First, let me just say that DERVVULFMAN was very helpful to me before. Trying to create a WOW/MMORPG styled message window (images, compatible with Mousie) and each time I put this in, and start it up after firign up an event to load it up, I get a NoMethodError for the messagegui_update with []=

Here's the script thus far.

Code:

# Message GUI Window Screen
#-------------------------------------------------------------------------------
# By JayRay 4/22/2014
#
# To begin, this will be a windowed 'Message' hud that I want to use with Mousie
# that comes up after certain variables are created, and a switch is turned on
#
# The screen will have variables change depending on events used on the screen
# for this map, while Game Switch 10, New Hero Game Switch is in operation.
#
# Game Variables 38-53 hold message data
# Game Variables 66-67 hold the window's initial x/y position
# Game Switch 25 sets its visiblity on/off
