Timer is not working smoothly

Getting Started Newbie Questions
#1

Hello dev’s

I am newbi to corona.

I am working on a game with OOP approach.

I have 2 classes/ lua.

  1. puzzle1 in which 

I am using timer in that class.

  1. Navigation Bar is a 2nd class for stuff like back to menu and all

so how can i stop timer from another class.

Here is some code.

Puzzle1.lua contains

function countTime()    

                i=i-1;

                showTimer.text=i;

                print(showTimer.text);    

end

 countTimer = timer.performWithDelay( 1000, countTime, 21)

Now i want to stop that timer and back_button’s listener is coded in navigation.lua

now in navigation i am doing like this

puzzle1 = require(“puzzle1”);

timer.stop(puzzle1.countTimer);

but it gives me a error (nil) value…?

Please reply me asap please.
