dealing with maintaining the web page state

[ambika]

hi frnds.. i designed a webpage which consists of a form.it includes 4 tables,3 checkboxes and a button.when the page is loaded it just shows the check boxes and the buttons.3 of the tables appears when respective check boxes are checked.the 4rth table appears on button click. once the values in the tables are set and submit is clicked it takes u 2 the second page.in the 2nd page i've a back button which takes u to the form if needed.now,if i click the back button it doesn't display the tables.it just shows the 3 check boxes and the button.i need the page to be displayed in the same manner in which it was when u clicked the submit button. can anyone help?? i've used javascripting for handling events in check boxes and buttons.
thanks in advance
