A function is not running inside a script, help?

Hello, I am working on a game and I came across some type of bug.

It's when a player joins, it creates his data in a module, but in a script it creates string, number values n stuff. I use a function for that but for some reason. It's just not running. I even put a print in the top, but not running at all. Here's the code. Inventory is a module.

CreateValues = function(Plr)
	if Plr then
		if Inventory.DataExists(Plr) then
			local B = Instance.new("NumberValue", Plr)
			B.Name = "Candy"
			B.Value = Inventory.Inv[Plr.UserId]["Currency"]["Candy"]
			local A = Instance.new("StringValue", Plr)
			A.Name = "Backpack"
			A.Value = EquippedPack(Inventory.Inv[Plr.UserId]["Inventory"]["Backpack"])
		end
	end
end

EquippedPack = function(Backpacks)
	for i,v in pairs(Backpacks) do
		if v[3] == true then
			return i
		end
	end
end

game.Players.PlayerAdded:Connect(function(Plr)
	Inventory.CreateData(Plr)
	CreateValues(Plr)
end)
