Architecture issue

[C0m4]

Hi

I'm writing a parking meter application - it must calculate the payment based currentTime minus parkingBegin time.
The app must be fool-proof, also.
I've created 4 input fields - one for every digit in 24h format, input fields are limited to 0-2,0-9,0-6,0-9.
To access these input fields i've used ENTER_FRAME event, which calls function which checks whether input1 is filled, than advances to input2 and so on, thus making it possible to only enter proper digits in proper cells.

the question is following: after each calculation attempt triggered by user entering digit in input4 and pressing enter, the entire procedure must be started over. What is the correct way to return/close all open functions/procedures/calls/whatever.
I have no experience in OOP - this is my first app, so my question might sound a bit dumb...

Welcome C0m4

What are those 4 input field stands for?

You mean "Restart" the application? You can make a function to reset all variables, remove listeners & start over again.

thanx
4 input fields for 4 digits in 24h time format
ex. if user inputs 13:40 as a parking start time field input1 to input4 will have values of 1, 3, 4, 0 respectively.

Yeah, restart the application.

I've created a function to reset vars and remove listeners.
so now i have calcStart() which calls calcDispatcher() which calls VariablesReset() which in turn calls calcStart() and so on on each program loop.

From what i know about programming this is not the right approach, however I'm not sure how to make it the right way.

Why do user input the time?

Could you explain a little bit more and the full story of your application?

The app is a parking meter. The user is cashier in an underground parking lot.
the program calculates payment based on the difference between the current time and the time user enters.

Anyway, I (think I) have figured out what was wrong, or rather how to do it right(or better) way.

Here is the code. it's working, handling input errors, etc. Requires some visual improvements and cleanup tho, will do a bit later.

The user should enter their Car Number and their Licence Number (optional) and when hit enter button, the application will store the arrival time with that user object. And when user leave, the application subtract it from the current departure time.
