ServerScriptService Is Not A Valid Member Of DataModel ?

I Have Been Losing My Sanity And The Will To Continue Coding Even Though It Is The Most Favourite Activity For Me To Do In The Meantime.

It Works Swiftly In Studio Mode But Not In Game

"ServerScriptService Is Not A Valid Member Of DataModel Stack Begin Script' Players.GizmoProductions.PlayerScripts.ModePickToText ', Line 6 Stack End"

Main = script.Parent.Parent

game.Workspace.NumberPlayers.Changed:connect(function()
    wait(0.5)
    if game.Workspace.NumberPlayers.Value >= 1 then
        game.ServerScriptService.ModePicker.Disabled = false
        game.SoundService.DrumRoll:Play() Main.PlayerGui.ModePickGUI.RoundShadow:TweenPosition(UDim2.new(0.314,0,
0.343,0)) 
        wait(5)
        local Rand = game.Workspace.Mode.Value
        Main.PlayerGui.ModePickGUI.RoundShadow.DropShadow.Namez.Text = Rand
    end
end)
