GameSerivce is not a valid member of DataModel?

Hia,

I'm trying to make a Class Selector, using this tutorial: https://www.youtube.com/watch?v=t64gExqgPbM

However, I've run into some errors that I do not know how to fix.

Errors:

GameSerivce is not a valid member of DataModel "Game" - Server - Class_Giver:1

GameSerivce is not a valid member of DataModel "2022 V2 @ 10 Jan 2023 08:59" - Client - ButtonHandler:3

Scripts:

ButtonHandler:

local Background = script.Parent

local rp = game:GameSerivce("ReplicatedStorage") local Class = rp:WaitForChild("Class")

for _, button in pairs(Background:GetChildren()) do if button:IsA("ImageButton") then button.MouseButton1Click:Connect(function() Background.Visibile = false

        Class:FireServer(button.Name)
    end)

end

end

Class_Giver:

local rp = game:GameSerivce("ReplicatedStorage") local Class = rp:WaitForChild("Class")

local SS = game:GetService("ServerStorage") local Classes = SS:WaitForChild("Classes")

Class.OnServerEvent:Connect(function(Player,className) local Backpack = Player.Backpack

local selection = Classes:FindFirstChild(className)
if selection then
    local moveset = Classes:FindFirstChild(className) :Clone()
    moveset.Parent = Backpack
end

end)

How would I go about fixing this? When I load in, the buttons are clickable, but nothing goes into the player backpack, and the GUI stays visible, even after choosing a class.

Thanks in advance!
