how would I save a table to a datastore?

I am trying to store values such as coins in a table and then save the table. I have the values constantly being updated and pcall functions. Whenever I run the script I get the default value of coins and the pcall function error.

--Get The Service's
local replicatedStorage = game:GetService("ReplicatedStorage")
local timePlayedValue = replicatedStorage.PlayerStats:WaitForChild("TimePlayedValue")
local totalTimeValue = replicatedStorage.PlayerStats:WaitForChild("TotalTimeValue")
local httpsService = game:GetService("HttpService")
local dsService = game:GetService("DataStoreService")
local mainStore = dsService:GetDataStore("MainDataStore")

--Get The Gameplay Stats
local CompletedMissionsValue = game:GetService("ReplicatedStorage").GamePlayStats:WaitForChild("CompletedMissionsValue")
local FailedMissionsValue = game:GetService("ReplicatedStorage").GamePlayStats:WaitForChild("FailedMissionsValue")
local PreviousMissionValue = game:GetService("ReplicatedStorage").GamePlayStats:WaitForChild("PreviousMissionValue")
local TimesDiedValue = game:GetService("ReplicatedStorage").GamePlayStats:WaitForChild("TimesDiedValue")
local TrapsAvoidedValue = game:GetService("ReplicatedStorage").GamePlayStats:WaitForChild("TrapsAvoidedValue")
local TrapsFailedValue = game:GetService("ReplicatedStorage").GamePlayStats:WaitForChild("TrapsFailedValue")

--Get The PlayerStats
local CoinsValue = replicatedStorage.PlayerStats:WaitForChild("Coins")
local DateFirstJoinedValue = replicatedStorage.PlayerStats:WaitForChild("DateFirstJoinedValue")
local RankValue = replicatedStorage.PlayerStats:WaitForChild("Rank")
local ExperienceValue = replicatedStorage.PlayerStats:WaitForChild("XP")

--Table To Store Data
local AllStatsTable = {CompletedMissionsValue,FailedMissionsValue,PreviousMissionValue,TimesDiedValue,TrapsAvoidedValue,TrapsFailedValue,CoinsValue,
	DateFirstJoinedValue,RankValue,ExperienceValue,totalTimeValue}


--Increment Time Values
incrementor = coroutine.create(function()
	while wait(1) do
		timePlayedValue.Value = timePlayedValue.Value + 1
		totalTimeValue.Value = totalTimeValue.Value + 1
	end
end)

coroutine.resume(incrementor)

--FIX DATASTORE
game:GetService("Players").PlayerRemoving:Connect(function(player)
	local success, err = pcall(function()
		mainStore:SetAsync(player.UserId,AllStatsTable)
	end)
	if err then
		print("error saving")
	end
end)

game:GetService("Players").PlayerAdded:Connect(function(player)
local success, err = pcall(function()
		local data = mainStore:GetAsync(player.UserId)
		if data then
			print(data[7])
		else
			print("no data")
		end
	end)
	if err then
		print("error saving")
	end
end)
