[HELP][LUA] Need help!

Hi!
I have a problem!
I'm trying to make a program that prints the time and a button to exit it.
I can run the program but the button won't do anything.

Heres my code:

Spoiler

function main()
term.clear()
term.setBackgroundColor(1)
term.setTextColor(32768)
term.clear()
term.setCursorPos(1,1)
print("The time is: ")
term.setCursorPos(1,3)
print(textutils.formatTime(os.time(), true))
term.setCursorPos(1,5)
print("[Exit]")
slc = 0
sleep(1)
main()

while true do
event, button, x, y = os.pullEvent("mouse_click")
if event == "mouse_click" then
  if slc == 0 then
   if x >= 1 and x <= 6 and y == 5 and button == 1 then
  term.clear()
   term.setCursorPos(1,1)
   print("Exited!")
   sleep(5)
	os.reboot()
	else
  main()
end
end
end
end
end




main()

What am I doing wrong?

you forgot the end at the end of your function

function main()
term.clear()
term.setBackgroundColor(1)
term.setTextColor(32768)
term.clear()
term.setCursorPos(1,1)
print("The time is: ")
term.setCursorPos(1,3)
print(textutils.formatTime(os.time(), true))
term.setCursorPos(1,5)
print("[Exit]")
slc = 0
sleep(1)
end
main()

while true do
event, button, x, y = os.pullEvent("mouse_click")
if event == "mouse_click" then
  if slc == 0 then
   if x >= 1 and x <= 6 and y == 5 and button == 1 then
  term.clear()
   term.setCursorPos(1,1)
   print("Exited!")
   sleep(5)
        os.reboot()
        else
  main()
end
end
end
end

I want it to update the time automaticly and then print the updated time.
(Sorry for any bad English)

No need to be sorry for the language my english is not better :D/>

here is the code for autoupdating time

function main()
while true do
term.clear()
term.setBackgroundColor(1)
term.setTextColor(32768)
term.clear()
term.setCursorPos(1,1)
print("The time is: ")
term.setCursorPos(1,3)
print(textutils.formatTime(os.time(), true))
term.setCursorPos(1,5)
print("[Exit]")
slc = 0
sleep(1)
end
end

function catchmouse()
event, button, x, y = os.pullEvent("mouse_click")
if event == "mouse_click" then
  if slc == 0 then
   if x >= 1 and x <= 6 and y == 5 and button == 1 then
  term.clear()
   term.setCursorPos(1,1)
   print("Exited!")
   sleep(5)
        os.reboot()
        else
  main()
end
end
end
end

while true do
 parallel.waitForAny(main, catchmouse)
 end

Thank You!
