local d = false
script.Parent.MouseButton1Down:Connect(function()
    local h = script.Parent.Parent.Parent.Parent.Parent.Character:FindFirstChild("Torso")
    local s = game.Workspace.ToSpawn
if d == false then
    d = true    
    h.CFrame = s.CFrame
    for i = 30,0,-1 do
        script.Parent.Text = i
        wait(1)
        if i >= 0 then
            script.Parent.Text = "Teleport to Spawn"
            d = false
        end
    end
