im trying to make it so when the player double taps W it will make them run but as of currently im just stuck here not knowing how to script the rest

heres the code

local Service = game:GetService("ContextActionService")

Service:BindAction("Humanoid SpeedBoost", function(LeftShift, InputState, InputObject)
	if InputState == Enum.UserInputState.Begin then
		script.Parent.Humanoid.WalkSpeed = 32
		print("It Works")
	else
		script.Parent.Humanoid.WalkSpeed = 16
	end
end, false, Enum.KeyCode.W)
