Calculating date in Custom Object

All,
 
I am requesting for some assistance with a trigger I am trying to create within my custom object name  Judgment_Event__c .
 
In the Judgment_Event__c I have the following fields below.
 
Action_Type__c                  (picklist)
 
Recording_Location__c     (picklist)
 
Expiration_Date__c            (date)
 
Recording_Date__c             (date)
 
Years__c                                (Number)
 
 
In my Trigger when Action_Type__c  = = ‘Recording’
And when Recording_Location__c   = = ‘County’
 
When a user enters a value in the Years__c field, I would like the number to be automatically be added to the date in the Recording_Date__c and the final calculation will be automatically populated in the Expiration_Date__c. This will happens whenever a user creates a new record or edits the information.

Below are the coding that I have for now, it is not much since I am a beginner in Apex.

your help will be greatly appreciated.

trigger NewYear on Judgment_Event__c (before insert,before update) {
    
    for(Judgment_Event__c JE: Trigger.new){
        if(je.Action_Type__c == 'Recording' && je.Recording_Location__c == 'County' && je.Years__c  != null && je.Recording_Date__c != null){
          je.Expiration_Date__c =  je.Recording_Date__c.addyears(Integer.valueof(je.Years__c));
        }
    }
}

Try the above code and let me know, if it works for you

Thanks,

Hi - I have a question. You mentioned Year is number field. What type of calculation your doing for Expiration_Date__c? 

Let take this example.
If the user enter value in the year field as 4, then recording date will be today(31-12-2014) and Expiration date will be (31-12-2018). Is my understanding is correct?

Thanks,
Karan

Yes it is,

if a user enter a  date in the recording date field such as 1/4/2014 and then the user enters 4 in the Years field, then in the Expiration date field, the value will be 1/4/2018

thank you for clarifying this to me. I should wrote an example to you earlier

Karanraj,

Thank you for your help  on this . I really appreciate it. I am studying your code to know what updates you did to make this trigger works. 

Do you know of any Apex trigger beginner tutorials I could learn from? I am looking for a real practical website for beginners. 

Currently, I ordered this book http://www.amazon.com/gp/product/0596009208/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1  so that I can learn Java as well. 

Thanks.
