session variables and form

hello all.. in my site, where im using phpscript, some users are allowed to del/modify contents of the database. for this they have been provided login name and password, after user loggs into the secure area, session starts. since here, user can modify/del contents of database, i needed to use many forms. arrays are used to store the checkbox, textbox values which user wants to modify. since these values are submitted thru forms in session, when browsers back button is pressed, it forces to press refresh button, to retrieve the values. can anyone help me to know how to pass variables to other pages in session using FORM POST or is it efficient to use session variables for all these values submited via FORM?? smita _________________________________________________________________ Chat with friends online, try MSN Messenger: http://messenger.msn.com
