Re: cannot index a table loaded as a chunk

[Ben Sunshine-Hill <sneftel@...>]

I'm wildly guessing you're executing luaL_loadfile, but never
executing the resultant chunk.

A chunk is a function. That's all it is. Commonly, it's a function
which happens to set a lot of global variables, but that's more a
convention than anything else. The point is, all luaL_loadfile does is
push a function onto the stack. If you don't execute it, it does
nothing.

Of course, it's possible your problem lies elsewhere entirely. If so,
post your code... it makes it much easier to troubleshoot.
