attempt to index nil with number when adding another data value?

So I made a dataStore script and its worked perfectly until I added a new variable "SpinVisibility"

im not sure whats exactly wrong with it but I keep getting the error

"line 99 attempt to index nil with number"

now I got this last error for my HasGame variable, and I found the solution to that was that I forgot to set it in both the table

this part

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

and this part

    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]
        SpinVisibility.Value = data[8]

so tldr: I only made 6 values in the first one but I forgot about HasGame and in the 2nd part there were 7 values and thats how I got the error "attempt to index nil with number" and I also changed "player" to "plr" as its a script in serverscriptservice

When I fixed those parts my Spin Gui worked perfectly, but I needed a new variable for the visibility of the spin button so the player doesnt abuse it when they rejoin

and thats how it all led here, sorry if it seems like a life story but ever since ive added the SpinVisibility variable its given me the same error on line 99

HasGame.Value = data[1]

that part

ive checked for everything wrong with it and tried to fix it like i fixed the hasgame variable but nothings worked, tell me whats wrong with it please

heres the full datastore script

local DataStoreService = game:GetService("DataStoreService")
local DataStore = DataStoreService:GetDataStore("Ballin2")
local replicatedStorage = game:GetService("ReplicatedStorage")
local saveRemote = replicatedStorage:WaitForChild("Save")



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

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


    local success, err = pcall(function()
        DataStore:SetAsync(player.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(player) -- When a player leaves the game
    saveData(player) -- Save the data
end)

game:BindToClose(function() -- When the server shuts down
    for _, player in pairs(game.Players:GetPlayers()) do
        saveData(player) -- 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 SpinVisibility = Instance.new("BoolValue", folder)
    SpinVisibility.Name = "SpinVisibility"



    --visibiliy of spin button variable

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

        data = DataStore:GetAsync(plr.UserId)

    else

        HasGame.Value = false
