Okay, I'm relatively new to programming as a whole (done some games/utilities in C# and that's it) and I need help. Ever since I first discovered how to work the editor I've wondered how to script, and wanted to be able to access the Adv. script area to learn editor scripting.
Until a few days ago I kept putting off learning scripting because I really didn't want to spend the time learning a new programming language. However since I had some free time I decided to try. Mainly through trial and error I've learned a lot about Lua since then, and have built a program that can do what is required for the first 3 steps of the Lua excercises but then I get to the table and I have no clue how to get that to work at all. The manual is incredably vague when it comes to tables, and the code it tells you to use to make a table doesn't work. Can anyone tell me how to make a table? That's really all I think I'll need to know to complete the majority of the training things, other than 9 which will take some in-depth searching about recieving input I'm sure (C# seems much better in that regard...just a simple "int.parse (textboxname)"...). Thanks for any help!

On a side note, the advanced scripting forum isn't a holy grail of scripting information; on the contrary, its mainly me complaining that I can't get simple things to work, and then occaisional threads that we move from the basic forum because people are posting scripts on how to do stupid things like make spheres of Gaifen around unsuspecting newbs (ok, haven't seen that one yet.. which would actually be kinda fun.. er.. Right.)
So don't think that you'll suddenly discover guides, examples, and instant knowledge of all that is lua, if/when you gain access to that forum.
Though feel free to add guides, examples, and such if you do ever get in.. 
As for your real question: uhh...
I don't know.
What was the question again?

Right.
Have you checked out the Lua Tutorials Wiki? It has a page on Tables, right at the top there.
Tables are basically just arrays, if you're used to them in other languages.. and I'd hope you are, since they're eminently handy; its hard to get by doing much without using one at some point. Or, it makes life easier to use them.

Thanks shig...actually I've never used tables before in my limited programming experiance...that wiki helped a lot.

The only thing I remember about lua, is that is doesn't produce a sorted numbered array when you itterate into one. Functions like tablesort etc were only semi effective at fixing it.
As a simple analagy, it's like counting from one to ten, then asking someone else to repeat it back, only to hear a jumbled, seemly randomized version of it.
That translates into '.. Is Crap' in my lingo, but maybe I was just being dumb and didn't get it tho. I figured it had something to do with the way lua writes a table to memory (ie 'badly').

Aren't LUA tables made from the wood of a Binary Tree?

Lol...it's not  ...I've pretty much decided that until I have a ton of free time again (school drains free time better than any game) I'm gonna spend my time having fun rather than trying to get Lua to work...I did managed to get half of my problem done...I just need to figure out how to make Lua convert a number into binary (I assume by ASCII you mean binary not some odd |-| | thing...)...those guides at least got me half-way
EDIT:ASCII Chars? Well, that'll probably prove to be very helpful information when I start trying to finish this again...thanks cold

No, they mean ASCII char not binary.
There is a function in lua that does that quite simply, but I think you'll have to search for it yourself on wiki. I don't want to give the game away.

Actually you can get a perfectly sorted output/iterator/loop, without having to sort the table (if you use the table as normal array).
Its just a single (short) line thats documented in the manual

Damn it! Now you've said that, I'll have to download Lua and learn to use it all over again.
