problem solved!
Without further ado, here's the error.. (I'm fairly new to the Lua language, as well)
please note, the (variable) parts of the functions were just put in to see if I could load them that way based off a tutorial or other I read up on (google failed me…) and the error has not changed.
The API:
The Error:
addendum to prior note: whenever I have some other error in the code itself (say, lacking the second = for my comparisons) that error popped up instead. However, this error always comes back.
I'm quite sure it's related to my not being able to load the variables I set in the program itself to be used in the API functions, which is something I would very much like to know how to do. Unfortunately, I can't seem to find it- meaning it's probably so basic everyone knows… or simply can't be done.
I apologize in advance if my stupidity is offensive. :)/>/>

Without further ado, here's the error.. (I'm fairly new to the Lua language, as well)
Spoiler
The program:
local A = (1/96)
local L = 32
local F = (A*L)
Local V = 1
minerapi.checkFuel()
minerapi.single()
minerapi.down()
turtle.turnLeft()
turtle.turnLeft()
minerapi.single()
minerapi.finished()
please note, the (variable) parts of the functions were just put in to see if I could load them that way based off a tutorial or other I read up on (google failed me…) and the error has not changed.
The API:
--API for various mining requirements!
--[[
A = area in terms of fuel/slice widthwise
F is Fuel--L is Length--x is unuseable!!
V is for the variable in that function!
(I.e. x < L in length.. in up x < v!)
REQUIRED IN PROGRAM:
A = (width/96)
L = Length
F = (A*L)
V = variable for the function (i.e. v in placement functions determines how far the turtle moves in a direction)
