I am tring to store and display the number of requests that a user has submitted via a hidden field. I've created a form that does a some simple addtion. Everything works, but I need some direction as to how I can store each number the user puts in and to display them. Please see below: <?php if ( ! isset( $_POST['number1'] ['number2'] ) ) { $message = "Welcome to the numbers game!"; } $number1 = (int) $_POST['number1']; $number2 = (int) $_POST['number2']; $result = (int) $number1 + $number2; $num_selections = (int) $POST['num_selections']; $num_selections++; // this is my attempt at collecting

This will only store the num_selections for *this request*. Each time you submit a form, it is a new request. To store information over requests most people would use session variables: http://www.php.net/manual/en/ref.session.php -- Teach a person to fish...
