When I save this code as a close.lua file and run dofile("close.lua") nothing happens. Please help.

gpio.mode(4,gpio.OUTPUT)
gpio.write(4,gpio.HIGH)
gpio.mode(3,gpio.OUTPUT)
gpio.write(3,gpio.LOW)
gpio.mode(3,0)

gpio.mode(3,0)

makes no sense to have in this code. But it's unlikely the problem here.
Have you checked that D3/D4 do not have HIGH resp. LOW?
What did you expect will happen?
