Hey… i got an error during my program. i've made a "Jail-System" that shows me which doors in my jail, that are open. but in a "select-an-option" part of my code, then if i type in anything, it just says:
startup4:93: attempt to compare nil with number

Can anyone help me out of this problem, and tell me what attempt to compare nil with number would mean?



my code is here: – BIG CODE – be careful –
Spoiler

Without taking the time to read through the code, "Attempt to compare nil with number" is exactly what it says. You attempted to compare a nil value (IE: A value that's never defined) with a number.

Change:

a, b= os.pullEventRaw()
if a == "key" then
to

b = os.pullEvent("key")
You can add

os.pullEvent = os.pullEventRaw
at the top of the code.

if b==208 and h<l then
Where is "L" defined? There is your nil error.

Well, Im here to tell something a little off-topic:
Use tables (the {} thingies) to define your variables.
To define all the "-" in the table, use this code:

Example = {}
for XD = 1,42 do --Replace 42 with the number of "-" 's
Example[XD] = "-"
end
Don't kill me if this doesn't work, just leave me a note about it not working.
Im sitting at a school computer, so I can't check the code for workingness…
Hope I helped.

I'm not sure if that was what they were referring to. I noticed this:

and h<l

(The character after the '<' sign I thought to be a letter, if it isn't then sorry; but I think that it is :P/>/>)

It is indeed the letter L. Good spotting.

Also, I don't know if it is the forums, but if not, you may benefit with a little proper formatting and spacing. That code is very difficult to look at.

I know what a less than sign is, the fact that you go to the forums instead of actually reading your code is annoying, cause you then act like I don't know proper english. Thank you for your time, but I'm done here.

Guys the error states that it was comparing(The < sign compares) to a nil(The Letter "l") with number. Replace the "l" with the number "1" or whatever you want it for, and that should work.

Yeah, just making sure that the creator of this post knows, because he doesn't seem to get it from viewing past responses…

Thanks for that. Many comments. I tried all the things that you guys posted, and now it works fine, but i cannot move the [open/close doors] anymore, that i could before the error. Why, and how.i will post my code later, cause i am at school.
