The code you've posted appears to have some issues and won't work as intended. I will explain what it should do conceptually and highlight the mistakes:

What the code is trying to do:

1. Module Script: It defines a module script that provides an add function for adding two numbers.

   • The add function takes 2 arguments (a and b) and returns their sum.

2. Server Script: It attempts to import (require) the module script and use the add function to compute the sum of 4 and 6, resulting in 10.

Issues in the Code:

1. Module Script Placement:

   • The module script needs to be placed inside ReplicatedStorage (or another accessible location) in Roblox Studio. You need to ensure there's a module script named moduleScript in the ReplicatedStorage.

2. Requiring the Module:

   • In your server script, the line local add = require(module.add) is incorrect. When using require with a module script, you should provide the module instance (module in your case), not its internal properties or methods. You cannot require a specific function of a module – you require the entire module first and then access the function.

3. Using the Function:

   • After requiring the module, you need to call its add function like module.add(4, 6) rather than trying to require the function.

Corrected Code:

Module Script (moduleScript in ReplicatedStorage):

local module = {}

-- Adds two numbers
function module.add(a, b)
  local result = a + b
  return result
end

return module

Server Script:

local RS = game:GetService("ReplicatedStorage")
local module = RS:WaitForChild("moduleScript") -- Wait for the module script in ReplicatedStorage

local requiredModule = require(module) -- Require the whole module
local result = requiredModule.add(4, 6) -- Call the 'add' function
print(result) -- Output 10

Explanation of the Corrected Code:

1. Module Script:

   • It defines a reusable add function inside the module table, which is returned at the end of the script. Other scripts can require this module to use its functions.

2. Server Script:

   • It uses WaitForChild to get a reference to the moduleScript in ReplicatedStorage.
   • The require function loads (or imports) the module, returning the module table.
   • The add function is called with arguments 4 and 6, and the result is printed as 10.

Output:

When corrected, the code will output:

10
