Why is this error popping up?

<eof> expected means you have too many ends somewhere in your code. Proper indentation can reveal this:

shell.run("clear")
print("Welcome to MoRBiiD's cannon control terminal!")
sleep(5)
print("What is your command?")
print("arm, deactivate") -- No deactivation yet...
local input = read()
if (input) == ("arm") then 
  shell.run("clear") 
  print("Loading...") 
  sleep(2) 
  shell.run("clear") 
  print("Fire, arrow or tnt?") -- No TNT yet...
  local input = read()
  if (input) == ("fire") then
    shell.run("clear")
    print(".")
    sleep(1)
    shell.run("clear")
    print("..")
    sleep(1)
    shell.run("clear")
    print("...")
    sleep(1)
    shell.run("clear")
    redstone.setBundledOutput("back", colors.red)
    sleep(1)
    redstone.setBundledOutput("back", 0)
    print("Done.")
  end --#here
  elseif (input) == ("arrow") then
    shell.run("clear")
    print(".")
    sleep(1)
    shell.run("clear")
    print("..")
    sleep(1)
    shell.run("clear")
    print("...")
    sleep(1)
    shell.run("clear")
    redstone.setBundledOutput("back", colors.white)
    sleep(1)
    redstone.setBundledOutput("back", 0)
    print("Done.")
  end
end -- <eof> expected?
sleep(2)
shell.run("startup") 

Also, I'd take a look at textutils.slowPrint ;)/>

thx it worked! i didnt think the problem was that i had too many "end"s but that i needed another (end of function EXPECTED) Now to blow up my friend's house > :D/> and btw i never thought that any slow print was possible, so thats why there are so many print>sleep>clear mini functions, thx for the advice!

eof stands for end of file (if there are too many ends, it'll do something like '<eof> expected').
