Countdown Program for Nuclear Reactor

Hey Guys,


I need a program that I can control my reactor. It should run automatically a certain time and then turn off. In addition, it should automatically perform an emergency shutdown when a redstone signal comes from the left. I have written a program, but unfortunately it does not work. I hope you can help me.

Many thanks!

Here is the code:

local monitor = peripheral.wrap("top")
monitor.clear()
monitor.setTextScale(1.5)
monitor.setCursorPos(2,3)
monitor.write("<Reaktor 1 AKTIV>")
monitor.setCursoPos(4,3)
monitor.write("Automatische Abschaltung in:")
monitor.setCursorPos(6,3)
redstone.setOutput("right", true)
monitor.write("3:00")
sleep(1)
for minutes = 2, 0, -1 do
for seconds = 59, 0, -1 do
monitor.clear()
monitor.setCursorPos(2,3)
monitor.write("<Reaktor 1 AKTIV>")
monitor.setCursoPos(4,3)
monitor.write("Automatische Abschaltung in:")
monitor.setCursorPos(6,3)
monitor.write((minutes < 10 and "0"..minutes or minutes)..":"..(seconds < 10 and "0"..seconds or seconds))
sleep(1)
if redstone.getInput("left", true) then shell.run"Stoerfall"
end
end
redstone.setOutput("right", false)

monitor.clear()
monitor.setCursorPos(6,3)
monitor.write("00:00")
sleep(5)
monitor.clear()
monitor.setCursorPos(2,3)
monitor.write("<Reaktor 1 wurde abgeschaltet>")
sleep(20)
os.reboot()

Change

if redstone.getInput("left", true) then shell.run"Stoerfall"
end

To:

if redstone.getInput("left", true) then shell.run("Stoerfall")
end

Is it not working aside from that?

Besides what simon helped you with, what does it do that it shouldn't, what happens before it doesn't work, any information as to what the problem could be pointed towards?

Here's my take on it:

local monitor = peripheral.wrap("top")
monitor.clear()
monitor.setTextScale(1.5)
monitor.setCursorPos(2,3)
monitor.write("<Reaktor 1 AKTIV>")
monitor.setCursoPos(4,3)
monitor.write("Automatische Abschaltung in:")
monitor.setCursorPos(6,3)
redstone.setOutput("right", true)
monitor.write("3:00")
sleep(1)
for minutes = 2, 0, -1 do --#unclosed for loop
  for seconds = 59, 0, -1 do
    monitor.clear()
    monitor.setCursorPos(2,3)
    monitor.write("<Reaktor 1 AKTIV>")
    monitor.setCursoPos(4,3)
    monitor.write("Automatische Abschaltung in:")
    monitor.setCursorPos(6,3)
    monitor.write((minutes < 10 and "0"..minutes or minutes)..":"..(seconds < 10 and "0"..seconds or seconds))
    sleep(1)
    if redstone.getInput("left", true) then --#rs.getInput accepts only a single parameter, thus true is unnecessary and ignored.
      shell.run"Stoerfall" --#shell.run has to be called using parentheses "()"
    end
  end
  redstone.setOutput("right", false)

  monitor.clear()
  monitor.setCursorPos(6,3)
  monitor.write("00:00")
  sleep(5)
  monitor.clear()
  monitor.setCursorPos(2,3)
  monitor.write("<Reaktor 1 wurde abgeschaltet>")
  sleep(20)
  os.reboot()

Just indenting the code properly reveals a great deal.
