Hi All,

I have the following trigger that adds Revenue Schedule records on the Opportunity when the Opportunity is created.  I would like to update those records when the Opportunity Stage is changed to Closed Won.  I would like the Projected_Accrual_Date__c field on the Revenue Schedule records to be updated in case the Closed Date on the Opportunity is changed.  How can i accomplish this?  

Thanks in advance. 

trigger RevenueScheduleForecast on Opportunity (after insert) {

//When Onmark Oppty is created, a list of Revenue Schedule Records will be
//inserted into the Opportunity record.

List <Revenue_Schedule__c> RSToInsert = new List <Revenue_Schedule__c> ();

for (Opportunity oppty : Trigger.new) {

if(
(oppty.RecordTypeId == '012A0000000eLsf' ) ||
