[Lua][Error] Somthing i cant find :(

So i am trying to make a program that opens a massive gate for me, just one problem im getting
bios:206: [string "gate"]:51: 'end' expected (to close 'while' at line 1)

while true do
  term.clear()
  term.setCursorPos(1,1)
  print("Open Or Close?")
  if input == "Close" then
	redstone.setOutput("back", true)
	sleep(1)
	redstone.setOutput("back", false)
	sleep(1)
	redstone.setOutput("back", true)
	sleep(1)
	redstone.setOutput("back", false)
	sleep(1)
	redstone.setOutput("back", true)
	sleep(1)
	redstone.setOutput("back", false)
	sleep(1)
	redstone.setOutput("back", true)
	sleep(1)
	redstone.setOutput("back", false)
	sleep(1)
	redstone.setOutput("back", true)
	sleep(1)
	redstone.setOutput("back", false)
	sleep(1)
	print("Closed Now!")
  end
  if input == "Open" then
	redstone.setOutput("right", true)
	sleep(1)
	redstone.setOutput("right", false)
	sleep(1)
	redstone.setOutput("right", true)
	sleep(1)
	redstone.setOutput("right", false)
	sleep(1)
	redstone.setOutput("right", true)
	sleep(1)
	redstone.setOutput("right", false)
	sleep(1)
	redstone.setOutput("right", true)
	sleep(1)
	redstone.setOutput("right", false)
	sleep(1)
	redstone.setOutput("right", true)
	sleep(1)
	redstone.setOutput("right", false)
	sleep(1)
	print("Open Now!")
  end
  else
	print("Command Not Recognised")
	print("Try With CAPS")
  end
end

Thanks in advance guys

while true do
  term.clear()
  term.setCursorPos(1,1)
  print("Open Or Close?)
  local input = read() --You never got input. Added this.
  if string.lower(input) == "close" then --string.lower allows any capitalization of the word to be correct.
	redstone.setOutput("back", true)
	sleep(1)
	redstone.setOutput("back", false)
	sleep(1)
	redstone.setOutput("back", true)
	sleep(1)

  elseif string.lower(input) == "open" then --elseif is your friend.

  --end before else block is incorrect.
  else

  end
end

Try that. See comments for corrections made.
