I have a script file embedded in the Workspace that contains functions. I would like call these functions from script files embedded in child objects of the Workspace. I don't want to have to copy and paste these functions into multiple script files. I figured the object oriented approach would be best if its possible.

The API protocol to call a function is simple: First, you push the function to be called; second, you push the arguments to the call; then you use lua_pcall to do the actual call; finally, you pop the results from the stack.
To call a function, type its name followed by parentheses. You can define a variable to accept the return value or use the return value in place of a variable.
Adding to Module Scripts To add a function or variable to the module which can be used in another script, type the module table's name, followed by a dot, and the name of the function or variable, like in TestModule. myVariable.
An alternative to _G is to use the also globally avaliable table, shared. Shared is used the same way _G is, but you must specify "shared" before the variable identifier, unlike _G, where you can merely write the name of the variable without the _G (not anymore in ROBLOX). Shared is used in the following context:
shared["variablename"] = value
Just like in the global stack, _G. Example usage of shared:
Script 1
shared["rprint"] = function(array) for i,v in pairs(array) do print(i, v) end end
Script 2
repeat wait() until shared["rprint"]
shared.rprint({"Hello, ", "How", " are", " you?"})
The output of this script would be "Hello, How are you?"

The simplest way would be to use _G or shared.
In one script,
_G.myFunction = function(Arguments)
-- blah
end
In another script, you would use this code.
repeat wait() until _G.myFunction ~= nil
_G.myFunction()
This would also work with the global table shared, instead of _G.
