Removing party member's name during battle (Ace Battle Engine)

[brendan fraser]

I'm using Yanfly's Ace Battle script and I want to know how to remove the names of party members during battle, so that only their portrait is shown.
 
I tried altering lines 1853 to 1861:
 

  #--------------------------------------------------------------------------
  # overwrite method: draw_actor_name
  #--------------------------------------------------------------------------
  def draw_actor_name(actor, dx, dy, dw = 112)
    reset_font_settings
    contents.font.size = YEA::BATTLE::BATTLESTATUS_NAME_FONT_SIZE
    change_color(hp_color(actor))
    draw_text(dx+24, dy, dw-24, line_height, actor.name)
  end

 
 
but I couldn't get anything to work.
 
Help is appreciated
