Mouseover Issue in WeakAuras

[Sweetsour]

Hello,

I'm working on a WeakAura that gives users the option to allow mouseover opacity on a select element. Everything's been going well, but I hit a snag with the mouseover script.

To preface, when the user toggles a mouseover checkbox in the Custom Options tab, it'll update an "isMouseover" variable on the specified element. This part works fine. However, within the "OnEnter" script, when trying to access the "isMouseover" variable, it comes back as nil.

aura_env.UpdateMouseover = function()
    for _,v in pairs(aura_env.config) do
        if (v.elementID ~= "" and v.isMouseover) then
            local element = _G[v.elementID]
            
            element.isMouseover = v.isMouseover
            element.noCombatOpacity = v.noCombatOpacity
            element.combatOpacity = v.combatOpacity
            element.mouseoverCombatOpacity = v.mouseoverCombatOpacity
            element.mouseoverNoCombatOpacity = v.mouseoverNoCombatOpacity
            
            print("Is Mouseover:",self.isMouseover) -- returns true/false
 
            element:SetScript("OnEnter",function(self) 
                    print("Is Mouseover in Script:",self.isMouseover) -- returns nil
 
                    if (self.isMouseover) then -- doesn't work
                        if (UnitAffectingCombat("player")) then
                            self:SetAlpha(self.mouseoverCombatOpacity)
                        else
                            self:SetAlpha(self.mouseoverNoCombatOpacity)
                        end
                    end
            end)
            
            if (UnitAffectingCombat("player")) then
                element:SetAlpha(element.combatOpacity)
            else
                element:SetAlpha(element.noCombatOpacity)
            end
        end
    end
end

I noticed that even if I run aura_env.UpdateMouseover() at WA_DELAYED_PLAYER_ENTERING_WORLD, element.isMouseover won't exist until I open WeakAuras' options, which I'm assuming means at the time of SetScript(), the .isMouseover variable doesn't exist on the variable yet. I'm not sure how to get around this :/
