I'm trying to gather some information from the user with regards to a lead, and then send them back to a page with a list of leads. The page I'm referencing in my method is not linking properly to the submit button and I'm at a loss as to why.  Here is the APEX and VF code.  The submit button on the VF page at /reject?id=rep.email&flip={!flip.id} should update three fields on the Lead Record and return the users to the /registrations?id={!rep.email} page.  Instead it's not updating the lead and is resetting the page URL to be /reject?id={rep.email}.

I have almost identical code working in another part of this class and am completely stumped why this would be happening.  Any clues? 

  public Contact rep = new Contact();
  public String rejectReason{get;set;}
  public String rejectDetail{get;set;}
  public Lead flip {get;set;}

 Public leadView(){
      Rep = [SELECT id, FirstName, LastName, Email, Accountid, Account.Type, Shark_Tank_Access__c FROM Contact 
              WHERE email =:ApexPages.currentPage().getParameters().get('id') limit 1];
  }
  
  public Contact getRep(){
  	return rep;
  }

public Lead getFlip(){
        flip = [SELECT id, Company, FirstName, LastName, Title, Registered_Rep__c, Registered_Rep__r.Email, Lead_Reject_Reason__c, Reject_Reason_Details__c, Rejected_by__c 
                FROM Lead WHERE id =: ApexPages.currentPage().getParameters().get('flip')];
    return flip;
   }
	

   public pageReference rejectLead(){
   		 flip.Rejected_by__c = ptnrRep.id;
   		 flip.Lead_Reject_Reason__c = rejectReason;
   		 flip.Reject_Reason_Details__c = rejectDetail;
   		 update flip;
 
   		 pageReference goBack = new      pageReference('/apex/registrations?id='+rep.email);
		 goBack.setRedirect(true);
 
   		 return goBack;
   }

 Visual Force Code:
