    public List<Opportunity> Opps  {get; set;}
    public List<OpportunitylineItem> Oppli  {get; set;}
   
    string id;
    decimal i =0; 
    decimal j = 0;
    
    public TVA_Billing_Items(ApexPages.StandardController myController) 
    {
    this.id = ApexPages.currentPage().getParameters().get('id');
     Opportunity o =[select id,name,Account.name,stagename,CloseDate,amount,probability,Header_Opportunity__c,Accountid,Opp_Line_Items_Count__c,Billing_Contact__c,No_Of_Months_for_Billing__c from Opportunity where id=:id];
     
     i = o.No_Of_Months_for_Billing__c;
     Opps = new List<Opportunity>();
     Oppli =new List<OpportunitylineItem>();
     
     for(i=0;i<o.No_Of_Months_for_Billing__c;i++){
     Opportunity LitOrd = new Opportunity();
      Opps.add(LitOrd);
      
       for(j=0;j<o.Opp_Line_Items_Count__c;j++){
          
             OpportunitylineItem LitOrdch = new OpportunitylineItem();
           
             Oppli.add(LitOrdch); 
          
        
        } 
       
       }
       }   
     

            
    public PageReference save() 
    {
    
     try{
     
            insert Opps;
                      
             for(Opportunity Opps1 :Opps){
                       
             for(opportunityLineItem oppli1 :Oppli){
             Oppli1.OpportunityId = Opps1.id;
            
            }
            
            }
            
            insert Oppli;
        }    

      catch (DMLException e) {
      ApexPages.addMessage(new ApexPages.message(ApexPages.severity.ERROR,'Oops An Error Occured!'));
      return null;
    } 
     
         return(new ApexPages.StandardController(Opps[0])).view();
       
 }
   
        }
