how would I save a table to a datastore? [closed]

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)
