What it means is a mainly, that you are trying to access a method of an object, but your object itself is nil. Essentially, this:
Code: 
nil.some_method

What is your code, not just that line. And I know for a fact that 'Character_Name' should be 'character_name', as case does matter in method calling (and just about anything).

Code: 
# The file name and hue of the character are set
   if actor != nil and (not actor.dead?) # When dead, it is erased for the time being...
     [B]@character_name = actor.character_name[/B]
     @character_hue = actor.character_hue
   else
     @character_name = ""
     @character_hue = 0
   end

This the code that I get the error on. The bold is the line that has the error.

Is there a way to fix it?

What was happenning was that when the character had no graphic I was getting that error, when I loaded a game i got that error.

I changed it to remove the Bold and underlined part so when the character died they wouldn't disappear, but that caused the characters graphic to change to the living person. Essentially I had two of the same graphics walking in a line. But I still had the no graphic error.

I then removed the part in just bold "and (not actor.dead?)", thinking that it would work. Well it did work [mostly]. I can start a new game without the character having a graphic, which is not a big deal since I worked around it. The graphic stays the same when the character dies, but a strange thing happens;

When a character dies the graphics change places until the character is revived.
EXAMPLE: I have two characters. One of them dies and it happens to be the leader. When the battle is over the leader is now in the back and the second character, the only living one, is now the leader.

Not what I was wanting, but interesting none the same.

-----------

All I was trying to do was make the script not make the character disappear when they die. I managed to change that and cause an effect that I wasn't expecting.

Thank you for the help SephirothSpawn.

You have to do more changes.

Line 131-145 method update_party_order
Code:

       dead_actors.push actor
     else
       alive_actors.push actor
     end
   end

 end

replace with

   end
