How do you enable/disable something (Particle Emitter)?

The particle emitter parts aren't working (Showing up and then disappearing, like a rain shower) Please help! Thanks

    wait(3) 
    game.Lighting.OutdoorAmbient = Color3.new(.2,.2,.5)
    game.lighting.Brightness(-10)
        wait(15)
        game.Workspace.Rain.ParticleEmitter.Enabled = true
        wait(120)
        game.Workspace.Rain.ParticleEmitter.Enabled = false
        wait(10)
