    How exactly do I reference a table from another document in my current one? For example: Sample1.lua contains SampleTable.Section (SampleTable does not have the "local" tag) and I'm trying to access it in Sample2.lua

    What I've tried so far is: Sample1.SampleTable.Section and Sample1:SampleTable.Section

    Either version has WoW toss up an error. I've checked the book, and I can't seem to find anything explaining how to correctly reference a function or variable from another lua file.

    Thanks in advance.

    MyAddon.toc:

     ##Interface: 30100
 ##Title: MyAddon
 MyAddon1.lua
 MyAddon2.lua

    MyAddon1.lua

     MyTable = {}
 MyTable.subtable = {}
 MyTable.subtable.apple = true

    MyAddon2.lua

     if MyTable then print("I found MyTable") end
 if MyTable.subtable then print("I found MyTable.subtable") end
 if MyTable.subtable.apple then print("Found the apple!") end

    Global tables are just that.. global. you don't need to prefix them with anything. As far as Lua is concerned, there are no "files" being loaded.

    Okay, the tables work now, but...

    I can't get it to reference functions...

     MyAddon1.lua
 function Sample1()
 print("meow")
 end

 MyAddon2.lua
 function Sample2()
 Sample1()
 end

    That's more or less what I'm trying to do, but MyAddon2.lua treats Sample1() as variable (or at least WoW does) and displays the error: "attempted to index global 'Sample1', returned a nil value "

    I've made sure that both .lua files are in the .toc file.

    Please don't post "more or less", since it always changes the semantics of what you are trying to do. The error message you are getting is that you are trying to index a nil value (as in you're using it like a table). If you were getting a call error, it would appear like "attempt to call global 'Sample1' (a nil value)". Please post your real code, and the real error message.
