[LUA][Question] Loop Code, Why isn't this working?

Ive been trying to loop the code below so it refreshes on the screen. The problem is the code just freezes and doesn't update. I have looked around and i cant understand why it isn't working. My current code is below

-- Reactor control: Turn off reactor
rout = colors.combine(rout,colors.red)
rs.setBundledOutput("bottom",rout)
-- Make sure input is intialised
rin=rs.getBundledInput("bottom")
mon = peripheral.wrap('top')
mon.setTextScale(1)
i = 1
while i  <= 5 do
	mon.clear()
	mon.setCursorPos(3,1)
	mon.write("========POISONSYS REACTOR=========")
	mon.setCursorPos(3,2)
	mon.write("=======CONTROL SYSTEM V1.0========")
	if(colors.test(rout,colors.red)) then
	mon.setCursorPos(1,4)
	mon.write("Reactor is  : OFFLINE")
	else
	mon.setCursorPos(1,4)
	mon.write("Reactor is  : ONLINE")
	end
	if(colors.test(rin,colors.black)) then
	mon.setCursorPos(1,6)
	mon.write("Wtr_cooling is  : ONLINE")
	else
	mon.setCursorPos(1,6)
	mon.write("Wtr_cooling is  : OFFLINE")
	end
	if(colors.test(rin,colors.green)) then
	mon.setCursorPos(1,8)
	mon.write("Ice_cooling is  : ONLINE")
	else
	mon.setCursorPos(1,8)
	mon.write("Ice_cooling is  : OFFLINE")
	end
	i = i + 1
	sleep(2)
  
end

Well, your code does have it limited to five refreshes two seconds apart. Why did you include that if you want it to continually refresh?

that was just part of a test, and it wasnt refreshing at all.

I don't see anything that would keep it from updating. I'll try it when I get home and see if it behaves the same for me.

One bit of advice though, instead of using colors.test use rs.testBundledInput. It seems to be less error prone

--replace stuff like:
if(colors.test(rin,colors.green)) then
--with
if rs.testBundledInput("bottom", colors.green) then

I've seen quite a few people on here that have had weird issues using the colors.test method.

ok ill try that, thanks

It works, if anyone wnats to use the updated code, here it is.
