attempt to call nil

Hello, my program is an all purpose OS that currently contains a calculator, a timer and a guess the number game. I tried running it, but after typing "go" to get in the program, it said "attempt to call nil" on line 173. Here is the code:


function guess()
do
numb = math.random(1,100)
tries = 1
triesmax = 7
version = 1.1
win = false
end

do
term.clear()
textutils.slowPrint("———————————–")
textutils.slowPrint("| Geuss the Number |")
textutils.slowPrint("———————————–")
print("Enter to continue")
io.read()
print("You have 6 guesses. Guess the number before you run out of guesses")
end

while true do
if tries > triesmax then
break
else
print("Guess. [1 - 100, whole number]")
guess = io.read()
guess = tonumber(guess)
if guess == numb then
win = true
break
else
print("Incorrect")
if guess > numb then
print("Your guess was too high")
elseif guess < numb then
print("Your guess was too low")
else
print("This is a bug. Inform the WILL OS lab")
end
tries = tries + 1
end
end
end

do
term.clear()
textutils.slowPrint("GAME OVER")
if win == true then
print("YOU WIN!")
else
print("YOU LOSE")
end
end


function options1()
input = read()

if input == "t" then
term.clear()
term.setCursorPos(1,1)
timer()
end

if input == "c" then
term.clear()
term.setCursorPos(1,1)
calculator()
end

if input == "?" then
term.clear()
term.setCursorPos(1,1)
Guess()
end
end

function home()
print "—————————————–"
print "|,.,.,.,.,.,.,.,.WILL OS ,.,.,.,.,.,.,.,|"
print "|[T] Timer | |"
print "|[C] Caculator | |"
print "|[?] Geuss the number| |"
print "—————————————–"
options1()
end

function title()
term.clear()
term.setCursorPos(1,1)
home()
end

function timer()
minutes = 0
hours = 0
function clock()
for seconds = 0, 60, 1 do
shell.run("clear")
print "WILL OS (copyright 2012)"
print "———————————"
print (hours, ":",minutes,":", seconds)
print "———————————"
print "ATTENTION: You must still use CTRL-T"
print "to exit this program"
print "A fix is on it's way!"
if seconds == (60) then
minutes = minutes + 1
clock()
end
if minutes == (60) then
hours = hours + 1
minutes = 0
end
sleep(1)
end
seconds = 0
end
clock()
end
end

function calculator()
print "WILL OS (copyright 2012)"
print "Do you want to add, subtract, multiply, or divide?"
op = read()
print ""
print "Enter first number"
num1 = tonumber(read())
print ""
print "Enter second number"
num2 = tonumber(read())
print ""

if op == "add" then
result = num1+num2
print(result)
sleep(4)
title()
end

if op == "multiply" then
result = num1*num2
print(result)
sleep(4)
title()
end

if op == "divide" then
result = num1/num2
print(result)
sleep(4)
title()
end

if op == "subtract" then
result = num1-num2
print(result)
sleep(4)
title()
end
end

print "——————————————-"
print "| Welcome to WILL OS! |"
print "——————————————-"
print "Current build - WILLOSDEVBUILD2"
print "Current Version - WILL OS ALPHA 2"

print "[go] Get Started!"
print "[info] Information. Read before use"

if input == "go" then
title()
end

if input == "info" then
info()
end

What is on line 173? (As much as i would love to count the lines I can't really be bothered)

line 173 is title()

under the if input == "go" bit

if input == "go" bit then?

nvm lol

try replacing that part with:
if input == "go" then
title()
elseif input == "info" then
info()
end

ok thanks ill try it

it's still doing it, but as soon as i boot the program up. I cant even input "go".

thats really weird.

are you sure that you have declared the variable 'input'?
put 'input = read()' before the 'if input == "go" bit

then it should work

Success?

hang on, ill try it

it's still giving the "attempt to call nil" message, but the first screen is working

this is wierd

Quad post! instead of quad post use the old edit button.

To op. Code tags ( [*code] –code [*/code] ) REmove the *s
Ask a pro section much better, ans faster, and the correct place to post this
Spoilers for long code. [*spoiler] –code [/*spoiler] remove 's

Try this one, it seems to work

Where have you defined a function for info() :?


Btw this should be in Ask a Pro.

lol soz sjele

Do not ask questions about code in programs section, moved to ask a pro.

ok, sorry, i'm pretty new here

I haven't defined the info() function yet, but that doesn't appear to have made a difference

Thanks Laywan, It worked!
