Need Help Character Window

[diosmx9 2]

Someone who helps me to help, happens to change uicharacter.py by one with another desing and I do not want to take a part of the skills.

this is the error : GameWindow.Open - <type 'exceptions.AttributeError'>:'NoneType' object has no attribute 'itervalues' 

this is the code : 

def __SetSkillSlotEvent(self):
        for skillPageValue in self.skillPageDict.itervalues():
            skillPageValue.SetSlotStyle(wndMgr.SLOT_STYLE_NONE)
            skillPageValue.SetSelectItemSlotEvent(ui.__mem_func__(self.SelectSkill))
            skillPageValue.SetSelectEmptySlotEvent(ui.__mem_func__(self.SelectEmptySlot))
            skillPageValue.SetUnselectItemSlotEvent(ui.__mem_func__(self.ClickSkillSlot))
            skillPageValue.SetUseSlotEvent(ui.__mem_func__(self.ClickSkillSlot))
            skillPageValue.SetOverInItemEvent(ui.__mem_func__(self.OverInItem))
            skillPageValue.SetOverOutItemEvent(ui.__mem_func__(self.OverOutItem))
            skillPageValue.SetPressedSlotButtonEvent(ui.__mem_func__(self.OnPressedSlotButton))
            skillPageValue.AppendSlotButton("d:/ymir work/ui/game/windows/btn_plus_up.sub",\
                                            "d:/ymir work/ui/game/windows/btn_plus_over.sub",\
                                            "d:/ymir work/ui/game/windows/btn_plus_down.sub")
