Why doesn't this chat & click script work? No errors are being outputted need help asap

local UIS = game:GetService("UserInputService")

local pressed = UIS:IsMouseButtonPressed(Enum.UserInputType.MouseButton1)

local incendio = "Incendio"

player.Chatted:Connect(function(message)

	if message:lower() == incendio:lower() then

		if pressed then

			event:FireServer("ballOfire")
		end

	end

	end)

No errors are being outputted, I simply want the localscript to fire a remote event when a player says "Incendio" and clicks
