Sound fails to play even though condition is met, no errors?

while true do
	wait(1)
	if game.Workspace.Variables.GasLevel.Value > 100 or if game.Workspace.Variables.Pressure.Value > 35 then
		script.Parent:Play()
		wait(3.98)
	end
end

Gaslevel and Pressure both work, and no errors are seen, but for some reason, no sound plays.
