Hello my particle emitter script only works in studio but i want it to work in game too. 1 color changed but the other one not. And how can i script the rate from the particle emitter?

Here is what i have!

game.Players.PlayerAdded:connect(function(player) 
    player.CharacterAdded:connect(function(char) 
        if char then
            local torso = char:FindFirstChild'Torso'
            local speed2 = Instance.new("ParticleEmitter", torso)
			local plr = game.Players.LocalPlayer
			local char = plr.Character
			local hum = char.Humanoid

hum.Running:connect(function(speed)
    if speed > 30 then
speed2.Color = ColorSequence.new(Color3.new(255,82,2),Color3.new(255,72,0))	
speed2.Texture = "http://www.roblox.com/asset/?id=281983189"
speed2.Size= NumberSequence.new(5)
speed2.LightEmission = 0.62
speed2.Lifetime = NumberRange.new(0,5)

    else
speed2.Color = ColorSequence.new(Color3.new(255,82,2),Color3.new(255,72,0))	
speed2.Texture = "http://www.roblox.com/asset/?id=281983189"
speed2.Size= NumberSequence.new(0)
speed2.LightEmission = 0
speed2.Lifetime = NumberRange.new(1)
    end
end)
        end
    end)
end)
