Why I can't save the Bool Value?

Basically, when player clicks the part, the boolvalue of boughtAK is supposed to be true. And when player leaves, the value is supposed to be saved, but it's not saving, any help?

local DS = game:GetService("DataStoreService"):GetDataStore("Exp")


game.Players.PlayerAdded:Connect(function(player)
	
	local boughtAK = Instance.new("BoolValue", player)
	boughtAK.Name = "boughtAK"
	
	workspace.Part.ClickDetector.MouseClick:Connect(function(clickPlayer)
		clickPlayer.boughtAK.Value = true
	end)
	
	
	local stats = DS:GetAsync(player.UserId)
end)

game.Players.PlayerRemoving:Connect(function(player)
	local allSaves = {}
	
	table.insert(allSaves, player.boughtAK.Value)
	DS:SetAsync(player.UserId, allSaves)
	
end)

You havent configured your table.insert correctly. First yoiu have the table, which you did, but thrn you need to add the position of which your inserted value will take once in the table. For this, add

#AllSaves +1

to put it in the first pos. Then, for the third parameter, add the thing you want to insert. Hope this helps. P.s. prob best if you don't parent your instance in the 2nd parameter as that is slower, but it's fine anyway

Try to change this inside the player added event. Instead of saying local stats = DS:GetAsync(player.UserId), do this:

local data
local success, errormessage = pcall(function()
	data = DS:GetAsync(player.UserId)
end)

if success and data then
	boughtAK.Value = stats.boughtAK
else
	print("Error while fetching the data!")
	warn(errormessage)
end

And inside the player removing:

local success, errormessage = pcall(function()
	local data = {
		boughtAK = player.boughtAK.Value;
	}

	DS:SetAsync(player.UserId, data)
end)

if success then
	print("Successfully saved data!")
else
	print("Error while saving the data!")
	warn(errormessage)
end

Let me know if it helped.
