[mrscale 1]

hi i'm trying to change tooltip of mining in characterwindow

i've before implemented other tooltip description like:

and as you see i've used the same code for all of them but when it come to 

SKILL_MINING it doesnt work.. why!

here's the code 

		elif player.SKILL_MINING == skillIndex:
			self.ClearToolTip()
			self.__SetSkillTitle(skillIndex, skillGrade)

			description = skill.GetSkillDescription(skillIndex)
			self.AppendDescription(description, 50)
			self.AppendSpace(5)
			self.AppendTextLine(localeInfo.TOOLTIP_SKILL_LEVEL % (skillLevel + 1), self.NORMAL_COLOR)
			self.AppendMiningSkillDefaultData(skillIndex, skillGrade, skillLevel, 70)


AND



	def AppendMiningSkillDefaultData(self, skillIndex, skillGrade, skillLevel, maxLevel):
		self.ClearToolTip()
		self.__SetSkillTitle(skillIndex, skillGrade)

		if 1 == skillGrade:
			skillLevel += 19
		elif 2 == skillGrade:
			skillLevel += 29
		elif 3 == skillGrade:
			skillLevel += 39
		elif 4 == skillGrade:
			skillLevel += 49
		elif 5 == skillGrade:
			skillLevel += 59
		elif 6 == skillGrade:
			skillLevel += 69
		server_value = get_server_skill_value(skillLevel + 1)
		final_value = server_value * 24.0

		description = skill.GetSkillDescription(skillIndex)
		self.AppendDescription(description, 80)
		self.AppendSpace(5)
		self.AppendTextLine(localeInfo.TOOLTIP_SKILL_LEVEL_WITH_MAX % (skillLevel, maxLevel), self.NORMAL_COLOR)
		self.AppendSpace(5)
		self.AppendTextLine(localeInfo.SKILL_MINING_DESCRIPTION % (final_value), self.POSITIVE_COLOR)



def get_server_skill_value(skillLevel):
		skill_server_values =[0.0, 0.05, 0.06, 0.08, 0.1, 0.12, 0.14, 0.16, 0.18, 0.2,
