Put your controller code also to identify the cause....

Hi Arpit,

Please find this below. 
public with sharing class AddnRemoveController {

   
   public List<wrapperClass> wrapList{get;set;}  
   public Integer counter{get;set;}
  
   
   public AddnRemoveController(ApexPages.StandardController controller){
   counter=0;
   wrapList= new List<wrapperClass>();
   wrapperClass wrp= new wrapperClass(new account());
   wrp.index=counter;
   wrapList.add(wrp);  
   }
   
   public pagereference addRow(){
   counter++;
   wrapperclass wrp1= new wrapperclass(new account());
   wrp1.index=counter;
   wrapList.add(wrp1);
   return null;
   }
   
   public pageReference removeRow(){
   
   
    /*
    for(Integer i=0;i<wrapList.size();i++){
            if(wrapList[i].index == rowNum ){
                wrapList.remove(i);     
            }
        }
    */
   if(wrapList.size()>1){  
   wrapList.remove(counter-1);    
   counter--; 
   }    
   return null;
   }
    public PageReference saving(){
        list<Account> updateAccountList;
        updateAccountList = new list<Account>();
        if(!wrapList.isEmpty()){
            for(wrapperClass accountWrapper:wrapList){
                updateAccountList.add(accountWrapper.act);
            }
        }
        if(!updateAccountList.isEmpty()){
            upsert updateAccountList;
        }
       ApexPages.Message myMsg = new ApexPages.Message(ApexPages.Severity.Info,'Record Saved Successfully.');
       ApexPages.addMessage(myMsg); 
        return null;
    }
   
   public class wrapperClass{
    public account act{get;set;}
    public integer index{get;set;}
    public wrapperClass(Account a){
    act=a;
    }
   }
}
