Been a while :P/>.

But, while making a program, i have been using dofile to access files. Here is an example of my API code:

Note that the API file name is API.lua


function lol()
  return lol
end
return API

This file is called program.lua


api = dofile("API.lua")
print(api.lol())

I get the error on program.lua, and its line 2, attempt to call nil ( a nil value ), which means that it is not a valid function that exists. Can you help me?

EDIT: Solved.

api = {}
function api.lol()
  return "lol"
end
return api

To clarify Creator's post, replace the content of API.lua with his code.

You may want to look at and/or use the os.loadAPI function, this may allow you to write a function which will load an API as you tried in you OP.

smigger22 has been on the forums for a long time, so I thought that this would be self-explanatory.
