Still getting the same error: attempt to index nil with number?

Alright so this is my 3rd time posting this, its more of an update if anything

the full dataStore script

local replicatedStorage = game:GetService("ReplicatedStorage")
local saveRemote = replicatedStorage:WaitForChild("Save")



local function saveData(plr) -- The functions that saves data

    local tableToSave = {
        plr.Data.HasGame.Value, -- First value from the table
        plr.Data.Hair.Value,
        plr.Data.Outfit.Value,
        plr.Data.Accessory.Value,
        plr.Data.Gender.Value,
        plr.Data.Blood.Value,
        plr.Data.Spins.Value,
        plr.Data.SpinVis.Value
    }


    local success, err = pcall(function()
        DataStore:SetAsync(plr.UserId, tableToSave) -- Save the data with the player UserId, and the table we wanna save
    end)


    if success then
        print("Data has been saved!")
    else
        print("Data hasn't been saved!")
        warn(err)       
    end
end

game.Players.PlayerRemoving:Connect(function(plr) -- When a player leaves the game
    saveData(plr) -- Save the data
end)

game:BindToClose(function() -- When the server shuts down
    for _, plr in pairs(game.Players:GetPlayers()) do
        saveData(plr) -- Save the data
    end
end)

--creating data

game.Players.PlayerAdded:Connect(function(plr)

    wait()

    local folder = Instance.new("Folder", plr)
    folder.Name = "Data"


    local HasGame = Instance.new("BoolValue", folder)
    HasGame.Name = "HasGame"

    local Hair = Instance.new("StringValue", folder)
    Hair.Name = "Hair"

    local Outfit = Instance.new("StringValue", folder)
    Outfit.Name = "Outfit"

    local Accessory = Instance.new("StringValue", folder)
    Accessory.Name = "Accessory"

    local Gender = Instance.new("StringValue", folder)
    Gender.Name = "Gender"

    local Blood = Instance.new("StringValue", folder)
    Blood.Name = "Blood"

    local Spins = Instance.new("IntValue", folder)
    Spins.Name = "Spins"

    local SpinVis = Instance.new("BoolValue", folder)
    SpinVis.Name = "SpinVis"



    --visibiliy of spin button variable




    ------------------------------------------------------------------------------------------------------------------------SAME HERE



    local data
    local success, err = pcall(function()

        data = DataStore:GetAsync(plr.UserId)

    end)

    if success then

        HasGame.Value = data[1]
        Hair.Value = data[2]
        Outfit.Value = data[3]
        Accessory.Value = data[4]
        Gender.Value = data[5]
        Blood.Value = data[6]
        Spins.Value = data[7]
        SpinVis.Value = data[8]

    else
        print("The player has no data!") -- The default will be set to 0
        HasGame.Value = false
        Hair.Value = "ConfirmedNewSave"
        Outfit.Value = "ConfirmedOutfitNewSave"
        Accessory.Value = "ConfirmedHornsNewSave"
        Gender.Value = "Male"
        Blood.Value = "Burgundy"
        Spins.Value = 8
        SpinVis.Value = true
    end

end)

like i said before ever since ive added the "SpinVis" variable to the data its all went wrong and the main line where im getting the error of "attempt to index nil with number" is here

if success then

        HasGame.Value = data[1]
        Hair.Value = data[2]
        Outfit.Value = data[3]
        Accessory.Value = data[4]
        Gender.Value = data[5]
        Blood.Value = data[6]
        Spins.Value = data[7]
        SpinVis.Value = data[8]

    else

HasGame.Value = data[1] is where the line of error is but it was working perfectly until SpinVis was added,,

A guy gave me this block of code that made sure I wouldnt get the uhh attempt to index nil with number error, im pretty sure im meant to replace the success part on my original script but im not sure where, you're free to test it all out yourself

local Success, Response = pcall(DataStore.GetAsync, DataStore, Player.UserId)
if (Success) then
    if (Response ~= nil) then
        -- Load data
    end
else
    warn(Response)
end

Im not sure what he meant by load data as im not even sure which part of my script is the load data part

probably this part here but i might be wrong

local data
    local success, err = pcall(function()

        data = DataStore:GetAsync(plr.UserId)

    end)

    if success then

        HasGame.Value = data[1]
        Hair.Value = data[2]
        Outfit.Value = data[3]
        Accessory.Value = data[4]
        Gender.Value = data[5]
        Blood.Value = data[6]
        Spins.Value = data[7]
        SpinVis.Value = data[8]

    else

I really dont know what else i could possibly do so yeah
