100% Test Coverage Code not deploying to production

I have written a trigger an handler with test code which works perfectly in my full config sandbox. However when I go to deploy to production I get errors which say it can't insert an opportunity line item.  Why would this work in the sandbox but throw this error in production? Can anyone help me? I've spent 2 days changing my code trying to get this work and it makes not sense. It seems it can't create a product line item.  I've added line numbers where the trouble is.

  lineItemTriggerHandlerTester.testAddDeleteLineItems System.DmlException: Insert failed. First exception on row 0; first error: CANNOT_INSERT_UPDATE_ACTIVATE_ENTITY, opportunityLineItemTrigger: execution of AfterInsert

Here is my class, trigger, and test code.


trigger opportunityLineItemTrigger on OpportunityLineItem (after insert,before delete) {

Add below line before line# 55
if(pCount == null) pCount = 0;

opp.PLIConsultingCalc__c = opp.PLIConsultingCalc__c + pCount;

Wow that worked, but the reality is it shouldn't be null. It seems the test code isn't creating the Opportunity Line Item and that's why the pCount is getting passed null. Is that something funny when dealing with pricebooks in test code? Why would it give me full coverage and allow me to created line items no problem in my full config sandbox. I'm writing a more complex trigger on my product line items and will surely run into this again.


Thanks heaps!
