I am trying to store the selected value of an item in my drop down list into a session variable after selecting it and pressing a button to add it to a session variable. My question is,how to display the selected item of dropdownlist on the dropdownlist of next page

If you are using cookies, it would be $_COOKIE['cookie_name'];
If you are using sessions, it would be $_SESSION['session_name'];
Can you verify that the data has been set?
