Why doesn't my script work in online mode but will work in studio? What am I doing wrong?

I'm trying to make a teleport which is FE compatible. When I tested it in studio, it worked, but going in-game, it doesn't. Is there something I'm doing wrong?

local player = game.Players.LocalPlayer
local char = player.Character

script.Parent.MouseButton1Click:connect(function(mouse)
        game.ReplicatedStorage:WaitForChild("Teleport"):FireServer()
    end)

game.ReplicatedStorage:WaitForChild("Teleport").OnServerEvent:connect(function()
    if script.Parent.Clicked.Value == false then
        char.Torso.CFrame = CFrame.new(Vector3.new(245.826, 77.351, 13.6))
        script.Parent.Clicked.Value = true
        script.Parent.Text = "Teleport to Runway"        
    elseif script.Parent.Clicked.Value == true then
        char.Torso.CFrame = CFrame.new(Vector3.new(26.8, 74.977, 41.499))
        script.Parent.Clicked.Value = false
        script.Parent.Text = "Teleport to Island"
    end
end)

"Teleport" is currently a RemoteEvent.
