OpenResty require cannot find modules - module

Question

After Apache has failed me miserably, I decided to go the OpenResty route.
So far, the Lua code is executing, however I opted to separate the generation in to multiple modules, to make the code more readable.
-- Define modules table
local modules = {
head = require("head"),
header = require("scripts.header"),
leftNav = require(".scripts.leftnav")
}
I've tried several methods of requiring files;
- I've taken one file out of the /scripts/ directory, and moved it to the root directory, file cannot be found
- I've tried referencing the /scripts/ directory with/out a period beforehand
and all is to no avail. The modules simply aren't found.
Is there some kind of special trick I need to find these files?
Here is an excerpt from the error log:

Answer 1

After some more researching, I found that using OpenResty, the period ( . ) doesn't refer to the current directory the executing script is located in, rather it refers to the directory that nginx is working in - in my case C:\nginx.
With this in mind, changing my resource locators from:
require(".scripts.head")
require(".scripts.header")
(...)
to
require(".html.mailarchive.scripts.head")
require(".html.mailarchive.scripts.header")
(...)
did the trick.
The new paths correlate to C:\nginx\html\mailarchive\scripts\head.lua, etc.
