Good morning all

For the past week I've been troubleshooting a script that I made based on a script posted somewhere here by Atomic Chicken, that allows for the creation of necromancer codices. The purpose of my script is to spawn a magic codex when used with modtools/reaction-trigger. Based on testing, it is able to spawn the books, but I can't seem to figure out how to make the scipt place the book under the worker's feet.

Here's the script in the raw, please excuse all the comments. As is it will spawn a codex and it will show on the stocks screen, but it's location is a mystery.

 print([[ Spawn spellbook.lua
 This script is designed to work with a reaction to spawn a spellbook.

 arguments:
 
 -material_id
Material book will be made of.

 -booktitle_name
Title of the book to be made. String must be contained within ' ' .

 -secret_id
Secret conveyed by the book (must use the IS_NAME of the secret). String must be contained within ' ' .

 -copy
If this optional argument is included, the script will make the book be treated as a copy

 -location
Location which the book will spawn.

  To use:
 
 Create a file called "onLoad.init" in Dwarf Fortress/raw if one does not already exist.
 Enter the following:
  modtools/reaction-trigger -reactionName YOUR_REACTION -command [ Spawn-spellbook -material_id MATERIAL -booktitle_name "BOOK TITLE" -secret_id "SECRET ID" -location \\LOCATION -copy]
 
  such as:
 
  modtools/reaction-trigger -reactionName SPAWN_NECROBOOK -command [ Spawn-spellbook -material_id INORGANIC:SILVER -booktitle_name "The Necronomicon" -secret_id "the secrets of life and death" -location \\LOCATION -copy]

I'm open to any ideas. I'm still teaching myself LUA through scripts by other people, so please excuse if there's an obvious solution
