Hi
i think the probelm is not with the code ,because it was working fine for more than 3 months,and i can print the report with no problem and the calculation was fine.
but now when i want to print a report i have no result and the page is blank..
i am wondering if it is the server problem(do i need to restart it) or the database problem do i need to index it ,
please find attached code
thanks
