How do I recolor more than one unit in FEXP?

[LordPudding]

I'm completely new in working with FEXP, and while I've been doing fine in the most part, I have run into a problem that I haven't figured out the solution to yet. I haven't managed to create multiple recolored actor units. I managed to edit the first one, just by editing the original script that recolored a 'Soldier' unit, but then I didn't know what to do for the next one.  I tried copying the whole script and pasting a copy of it below the original, and then editing its properties, but that removed the modified colors of the original unit I edited.

  def self.has_key?(key, name = nil)
    if name.nil?
      return self.get_color(key, nil, 0, true).length != 0
    else
      result = self.get_color(key, name, 0)
      return result.nil? ? false : result.length != 0
    end
  end

(Spoiler for the script.)

I've tried also only copying specific parts, but that gives me a syntax error. What should I have been doing?
