Hello SFDC Gurus - request for help with Triggers on Case object !

I am learnig Apex coding using David Liu's Apex Academy and have a couple triggers on Case object 
WarrantySummary
CheckSecretInformation

All was well till I only had the WarrantySummary trigger but once I created the CheckSecretInformation trigger and try to insert/edit a case I get the error below ==> 

Error: Invalid Data. 
Review all error messages below to correct your data.
Apex trigger CheckSecretInformation caused an unexpected exception, contact your administrator: CheckSecretInformation: execution of AfterInsert caused by: System.DmlException: Insert failed. First exception on row 0; first error: CANNOT_INSERT_UPDATE_ACTIVATE_ENTITY, WarrantySummary: execution of BeforeInsert caused by: System.NullPointerException: Attempt to de-reference a null object Trigger.WarrantySummary: line 5, column 1: []: Trigger.CheckSecretInformation: line 32, column 1

Can you please help ?

Regards
Pallavi

You'll need to post your code; however, it sounds like your trying to do something on a variable that hasn't been intiizlied. This is typically seen when you've queried a record and are attempting to do something without checking if it's null. For example, let's say you had a text field that you were trying to do a string fuction against (e.g. equalsIgnoreCase). If it's null and you attempt to run a string function against it, you'll get just such an error.

Thank you so much Jason! Sorry it took so long to check and respond. I will initialize the variable and see how it goes. Thanks once again for replying!
