Help with NullPointerException in apex trigger

Please help I created an Apex Trigger to update a field if the total testing hours change below is the error I get.
CalculateBalanceOfCustom: execution of BeforeUpdate caused by: System.NullPointerException: Argument cannot be null.: Trigger.CalculateBalanceOfCustom: line 25, column 1".

Code:
trigger CalculateBalanceOfCustom on Custom_Programming__c (before insert, before update)
{
//SQL statement to lookup price
List<PricebookEntry> Pbe = [SELECT UnitPrice FROM PricebookEntry WHERE Product2.Name IN('Custom Development','Tape Drop')AND PriceBook2.Name='DAKCS'];
//New Values for loop
for (Custom_Programming__c cp:Trigger.new)
{
//Map old Values and ID
Custom_Programming__c oldcp = Trigger.oldMap.get(cp.ID);

//Tapedrop
if (cp.Custom_Type__c == 'Tape Drop' && cp.Total_Hours__c !=oldcp.Total_Hours__c)
{
cp.Testing_Balance__c = pbe[1].UnitPrice + (pbe[0].UnitPrice * cp.Total_Hours__c);
}

//No Billing Bug Fix
if (cp.Custom_Type__c =='No Billing' || cp.Custom_Type__c =='Bug Fix'&& cp.Total_Hours__c !=oldcp.Total_Hours__c)
{
cp.Testing_Balance__c = pbe[0].UnitPrice * 0;
}
//Everything Else
if (cp.Custom_Type__c !='No Billing' || cp.Custom_Type__c !='Bug Fix' || cp.Custom_Type__c!='Tape Drop' && cp.Total_Hours__c !=oldcp.Total_Hours__c)
{
cp.Testing_Balance__c =pbe[0].UnitPrice * cp.Total_Hours__c;
}
}
}

Thanks for any assistance you can give.

Was able to fix it by changing my code a little:

trigger CalculateBalanceOfCustom on Custom_Programming__c (before update)
{

//SQL statement to lookup price
List<PricebookEntry> Pbe = [SELECT UnitPrice FROM PricebookEntry WHERE Product2.Name IN('Custom Development','Tape Drop')AND PriceBook2.Name='DAKCS'];

//New Values for loop
for (Custom_Programming__c cp:Trigger.new){

//Old record values
Custom_Programming__c oldcp = Trigger.oldMap.get(cp.ID);

   //If total hours or custom type has not changed then bail
if(cp.Total_Hours__c==null || (cp.Total_Hours__c==oldcp.Total_Hours__c && cp.Custom_Type__c == oldcp.Custom_Type__c))
continue;

//Tapedrop3
if (cp.Custom_Type__c == 'Tape Drop')
{
cp.Testing_Balance__c = pbe[1].UnitPrice + (pbe[0].UnitPrice * cp.Total_Hours__c);
}
//No Billing Bug Fix
else if (cp.Custom_Type__c =='No Billing' || cp.Custom_Type__c =='Bug Fix')
{
cp.Testing_Balance__c = 0;
}
//Everything Else
else
{
cp.Testing_Balance__c =pbe[0].UnitPrice * cp.Total_Hours__c;
}
}
}

HI Jeff,
I see that line 25 is
cp.Testing_Balance__c =pbe[0].UnitPrice * cp.Total_Hours__c;

The best way to identify what value is null is to add system.debug() statements in every block of your code. With this you should be able to identify the argument that is null

This post gives good example of this error message https://salesforce.stackexchange.com/questions/45382/system-nullpointerexception-argument-cannot-be-null

Hope this helps you. Please mark this answer as best so that others facing the same issue will find this information useful. Thank you
