Hi,

     I've created page whenever click on add button two textboxes would be create.

When click on remove button textboxes would be delete. But when i delete Index [1] the textbox will deleted and when i  try to delete Index[4] below error occuring.. Error occuring only on remove method

My code everything is correct except below bug

   System.ListException: List index out of bounds: 3

public with sharing class textboxcls {

public PageReference save() {

List<Account> lst=new List<Account>();

for(wrapper w:lstwrap){
lst.add(w.acc);
}
insert lst;

return null;
}

public Integer rowId{get;set;}

public PageReference remove() {

system.debug('***********************************************************'+rowId);
lstwrap.remove(rowId);

return null;
}

public PageReference add() {

lstwrap.add(new wrapper(lstwrap.size() ,new Account()));

// system.debug('****************************size*****************************'+lstwrap.size());


return null;
}

public List<wrapper> lstwrap {get; set;}

public class wrapper {

public Integer Index {get; set;}
public Account acc {get; set;}

public wrapper(Integer i, Account a){

Index =i;
acc=a;
}
}

public textboxcls(){

lstwrap=new list<wrapper>();
lstwrap.add(new wrapper(0,new Account()));


}
