luaindex type

[CatoTheElder]

So, after about half dozen posts, I remembered I came here to ask about the luaindex type. I'm about 98% sure someone made that up, and I don't know what in the flying **** I need to pass. I tried the string 'skooma', but it didn't like that ... I know all about arrays, tables, items, and indices, so please don't give me some generic explanation about an index.

Specifically, the lua part of luaindex. Is it looking for an index to correlate to the array/table/object that holds .... the path to the lua compiler?!

If anyone could explain anything about it, I would greatly appreciate it.
