confusion

straight from iron will talent, i just added the confusion code to match the stun code:

passives = function(self, t, p)
        self:talentTemporaryValue(p, "confusion_immune", t.confusionImmune(self, t))
        self:talentTemporaryValue(p, "stun_immune", t.stunImmune(self, t))
    end,
    info = function(self, t)
        return ([[Dual-self mental sturdiness improves Mental Saves by %d, and confusion and stun immunity by %d%%.]]):
        format(self:getTalentLevelRaw(t)*6, t.confusionImmune(self, t)*100, t.stunImmune(self, t)*100)
    end,


    Result = nil value error:

    Lua Error: /data-Chrono_Xorn/talents/Chrono_Xorn.lua:533: attempt to call field 'confusionImmune' (a nil value)

    and this is the mental timed effects confusion code in the game:


newEffect{
    name = "CONFUSED", image = "effects/confused.png",
    desc = "Confused",
    long_desc = function(self, eff) return ("The target is confused, acting randomly (chance %d%%) and unable to perform complex actions."):format(eff.power) end,
    type = "mental",
    subtype = { confusion=true },
    status = "detrimental",
    parameters = { power=50 },
    on_gain = function(self, err) return "#Target# wanders around!.", "+Confused" end,
    on_lose = function(self, err) return "#Target# seems more focused.", "-Confused" end,
    activate = function(self, eff)
        eff.power = math.floor(math.max(eff.power - (self:attr("confusion_immune") or 0) * 100, 10))
        eff.power = util.bound(eff.power, 0, 50)
        eff.tmpid = self:addTemporaryValue("confused", eff.power)
        if eff.power <= 0 then eff.dur = 0 end
    end,
    deactivate = function(self, eff)
        self:removeTemporaryValue("confused", eff.tmpid)
        if self == game.player and self.updateMainShader then self:updateMainShader() end
    end,
}

and my talent which is needed because having a zillion bloated horrors dropping confusion on me all at once became just bad:


newTalent{
    short_name = "2_MIND",
    name = "2 Mountains Mind",
    --code adapted from iron will
    type = {"race/Chrono_Xorn", 1},
    image = "talents/overseer_of_nations.png",
    require = psi_wil_req3,
    points = 5,
    no_npc_use = true,
    no_unlearn_last = true,
    mode = "passive",
    stunImmune = function(self, t) return self:combatTalentLimit(t, 1, 0.17, 0.50) end,
    on_learn = function(self, t)
        self.combat_mentalresist = self.combat_mentalresist + 6
    end,
    on_unlearn = function(self, t)
        self.combat_mentalresist = self.combat_mentalresist - 6
    end,
    passives = function(self, t, p)
        self:talentTemporaryValue(p, "confusion_immune", t.confusionImmune(self, t))
        self:talentTemporaryValue(p, "stun_immune", t.stunImmune(self, t))
    end,
    info = function(self, t)
        return ([[Dual-self mental sturdiness improves Mental Saves by %d, and confusion and stun immunity by %d%%.]]):
        format(self:getTalentLevelRaw(t)*6, t.confusionImmune(self, t)*100, t.stunImmune(self, t)*100)
    end,
}


what is confusing it?
