Can't use While and Repeat?

Hello all,

So I made a program that listens for a redstone signal and when it is turned off it prints a message to a monitor. Since it's always litening I thought it would be useful to have an 'X' that exited the program. I implemented this, however now neither te redstone event nor the 'X' work. It doesn't make a difference whether I put the redstone code or the 'X' code first. Anybody got any ideas?:

mon = peripheral.wrap("right")
count = 0
term.clear()
term.setCursorPos(1, 1)
sleep(1)
print("Waiting for redstone input...")
print("Hold 'CTRL+T' to terminate")
term.setCursorPos(51, 18)
print("C")
term.setCursorPos(1, 18)
print("X")
term.setCursorPos(1, 4)
while true do
count = count+1
os.pullEvent("redstone")
if rs.getInput("bottom") == false then
  print(" ")
  print("Redstone input detected ("..count..")")
  mon.setTextColor(colors.red)
  mon.setTextScale(2)
  mon.clear()
  mon.setCursorPos(6, 2)
  mon.write("DOORS")
  mon.setCursorPos(5, 3)
  mon.write("OPENED!")
  sleep(2)
  mon.clear()
end
end
repeat
event, button, x, y = os.pullEvent("mouse_click")
if x == 51 and y == 18 then
term.clear()
term.setCursorPos(1, 1)
print("Waiting for redstone input...")
print("Click X to terminate")
term.setCursorPos(1, 18)
print("X")
term.setCursorPos(51, 18)
print("C")
elseif x == 18 and y == 1 then
sleep(1)
term.clear()
term.setCursorPos(1, 1)
error()
end
until nil

I would appreciate any help :)/>

The repeat until loop won't even run, because a while true do loop never finishes (unless terminated).
Why don't you put all in one loop?
Could look like this:

while true do
ev, prm1, prm2, prm3 = os.pullEvent()
  if ev == "redstone" then
	if rs.getInput("bottom") == false then
	print(" ")
	print("Redstone input detected ("..count..")")
	mon.setTextColor(colors.red)
	mon.setTextScale(2)
	mon.clear()
	mon.setCursorPos(6, 2)
	mon.write("DOORS")
	mon.setCursorPos(5, 3)
	mon.write("OPENED!")
	sleep(2)
	mon.clear()
	end
  elseif ev == "mouse_click" then
	if prm2 == 51 and prm3 == 18 then
	term.clear()
	term.setCursorPos(1, 1)
	print("Waiting for redstone input...")
	print("Click X to terminate")
	term.setCursorPos(1, 18)
	print("X")
	term.setCursorPos(51, 18)
	print("C")
	elseif prm2 == 18 and prm3 == 1 then
	sleep(1)
	term.clear()
	term.setCursorPos(1, 1)
	break
	end
  end
end

This worked, and fixed another problem :)/> Thank you so much!

P.S:

- snip -

Wouldn't my second 'end' terminate the 'while true' loop?

The end closes the block that the while began but there is no condition when 'true' will be false. To exit the while you could put a 'break' or if the while was in a function you could use 'return'. You would put either of those within an if block and test for some condition such as the x key being pressed.

Ah i see, i thought end would do what break did. New to coding :)/> thanks!
