Howdy Folks!  I am trying to write a trigger that will work like a roll up summary field.  I have to run this through a trigger as I cannot create a master detail relationship with a managed custom object.  This is using docusign.

The use case is this.  When a doc is marked as completed in the custom object Docusign status (dsfs__DocuSign_Status__c).  I need to get a count of items either completed or Denied and use that data to manage the Opportunity stage.

If status =complete, stage = Closed Won

if Status=Denied, Stage = Closed Lost

Has anyone run into this issue?!  I cannot believe I am the first one to need this automation.  Thanks folks!
