This is my code. When I launch it, it comes up with the error "Multiple Points." What does that mean?

I haven't found out why you get Multiple Points yet, but I'll point out something about your logo: In doublequote, and quote strings, the character escapes the next character.
Hence, when you print your logo, you'll find that some of the s are missing.
You should also use "term.write" instead of "write".

Try fixing this, then see if anything changes. I'll look into this multiple points error meanwhile.

Multiple points error is caused by your version string:

--API Variables
version = v1.0.0
--Actual Install

--API Variables -- Fixed
version = "v1.0.0"
--Actual Install

Put it in quotes, as shown above.

Alright, thanks.

But what other way can I write the logo?

I'd use

[[string]]

Here's an except, from tmart:

Edit: Forums doesn't like whitespace, as usual.

See it here: http://pastebin.com/nuX33xq7

I'm using it at line 22-34, to draw ascii art.

-only noticed this now-

I don't really do well with looking at a large page where I'm tempted to exit and facedesk for being lazy.
Only way I learned some LUA was with Casper's interactive tutorial. I learn from those simulations.

Sorry if I'm such a noob, guys. D:

You don't need to use "" quotes when you use [[[]].

When you get "Too many points", look for periods; you have multiple points unescaped, that are part of a number, e.g 1.0.0

If you're still getting too many points, repost your code.

Also in addition to everything that was already mentioned, you have this in your code:

fs.exists(disk/mainfiles/startup)

You forgot to encase the String in quotation marks, it should be:

fs.exists("disk/mainfiles/startup")

Look at this part of the code..

   print("We're sorry we couldn't continue your\ninstallation of ScarletOS. Please report the\nerror to Xemiru, the creator of ScarletOS.\nThank you for choosing ScarletOS! Goodbye!")
   print("Press any key to continue.")

I think this is it.

I'm at school right now, so I can't check. I'll check back into this later. [like an hour and 14 mins left.]

…Kill me.

This whole time, I was storing the wrong API in the file folder.

Well, thanks for all the help, I guess. :D/>/>

Haha, well, glad you found out your problem in the end. :D/>/>

Mhm. I put a note on my computer saying "Don't be an idiot."

Aaaaaand a new problem occurs.

attempt to call nil

-___-

Really…

I'll pastebin the code.

startup
http://pastebin.com/MepkrXBb

installAPI
http://pastebin.com/XytZAYUW

That warning message should always draw your attention to function calls. More often than not it's a typo in a function name / call or calling a function that isn't defined yet.
In your case you're calling menucontrol with a lowercase 'c', wheareas the function is actually defined as menuControl with a capital 'C'.
Don't feel bad though, happens to all of us. :D/>/>

Edit:
Also, I haven't looked into the loadAPI functionality yet, so I don't know if this might be a problem but:
Normally in Lua you have to define functions before you can use them within other functions, or else you'll also get an "attempt to call nil".
For example, within logo() you're trying to call slPrint(). But that is defined only after the logo() function.
So if the typo from above doesn't seem to be enough to get rid of the "attempt to call nil" error, then make sure that every function you're calling, is actually defined before you're calling it.

My 12 year old brain has been filled with complication. Lol. I'll take a look into it.

EDIT:
After school, that is.

I am getting multiple points on this code:

print("Enter number of head shifts:")
v=tonumber(read())
print("")
t=1
a=1
x=0
y=0
p=0
while t<=v do
print("state:"..a.." symbol:"..x%3.." position:"..p)
if a==1 then
if x%3==0 then
  x=math.floor(x/3)
  y=3*y+1
  a=2
  p=p+1
elseif x%3==1 then
  x=3*(x+1)+y%3
  y=math.floor(y/3)
  a=1
  p=p-1
else
  x=3*(x-1)+y%3
  y=math.floor(y/3)
  a=1
  p=p-1
end
else
if x%3==0 then
  x=3*(x+2)+y%3
  y=math.floor(y/3)
  a=1
  p=p-1
elseif x%3==1 then
  x=math.floor(x/3)
  y=3*y+2
  a=2
  p=p+1
else
  x=math.floor(x/3)
  y=3*y
  a=1
  p=p+1
end
end
t=t+1
end

I am new in all these stuff, how to check API? Firstly, this program was shorter. Then I added some lines of code, and multiple points started to appear. When I deleted new lines multiple points still haven't work. All other programs on same computer work

I would guess this is the culprit:

print("state:"..a.." symbol:"..x%3.." position:"..p)
You could try:

print("state:"..a.." symbol:"..(x%3).." position:"..p)

Now it works. Computer read x%3.. as x modulo 3.. which is number with multiple points. Thanks for help!
