    local name = UnitName(unit)
    local index = GetRaidTargetIndex(self.unit)
    if(UnitIsTapped(unit) and not UnitIsTappedByPlayer(unit) or not UnitIsConnected(unit)) then
      self.Name:SetTextColor(.6, .6, .6)
    else
      local color
      --snip
      if UnitIsPlayer(unit) then
        color = RAID_CLASS_COLORS[select(2, UnitClass(unit))]
      else
        color = FACTION_BAR_COLORS[UnitReaction(unit, "player")]
      end
      --snip end
      if(color) then self.Name:SetTextColor(color.r, color.g, color.b) end
    end
    self.Name:SetText(name)
  if unit == "target" then
    updateLevel(self, unit)
    end
  end
end
