I have written code for adding and removing dynamic rows.i am using same file for both ADD

and MODIFY operations.this page is working for ADD operation.

lets say for MODIFY operation one employee has added 3 rows and i need to display those rows
and user can edit thoese rows and finally these values will be submitted to database.

problem is coming in modifyRow() method.how to accomodate array values in the dynamic rows
in modifyRow() method.Please review the code in that method?while loading the values the

structure should be same as addRow() method?
