Another method of the class is called Lua

Attempt to call field'LoadShift' (a nil value)

local LoadShift = nil;
.
.
function LoadShift()

end

local loginObj = require("com.classess.loginpage1")
loginObj.LoadShift();

--- ---------Your class LoadShift---------------
 local LoadShift = {}
 .
 .
 function LoadShift:LoadShiftFunc()
 --do somthing
 end
 .
 .
 return LoadShift
----------- --------------------------

---------------------

local LoadShift = require "LoadShift"
LoadShift:LoadShiftFunc()< /pre> 

When I try to call a method of another class from another class, it displays an error message,

Attempt to call field'LoadShift' (a nil value)

This is my code,
loginpage1.lua

local LoadShift = nil;
.
.
function LoadShift()

end

loginpage2.lua

local loginObj = require("com.classess.loginpage1")
loginObj.LoadShift();

What’s wrong with my code, please help me solve this problem

Make your custom class like this

----------- -Your class LoadShift---------------
 local LoadShift = {}
 .
 .
 function LoadShift:LoadShiftFunc()
 --do somthing
 end
 .
 .
 return LoadShift
------------------- ------------------

Then need it and call the function

---- -----------------

local LoadShift= require "LoadShift"
LoadShift:LoadShiftFunc()
