I want to build a series of very simple pages as an exercise, where a variable is passed via a form from one page to the next, where a calculation is performed on the variable's numeric value, and then passed via a form to a third page. I can't seem to get it to work. The first page--I'll call it q1.php--has something like this: [code] <html> <body> <form action="q2.php" method="post"> <p> <b>1. Choose an option:</b><br> <input type="radio" name="q1" value="Increment"> Increment <br> <input type="radio" name="q1" value="NoIncrement"> No Increment<br> <br> <input type="submit" value="Go to the next page"> </form> </body> </html> [/code] Then, on the second page (q2.php): [code] <?php $score = 0; $q1 = $_POST['q1']; if ($_POST['q1'] == 'Increment') $score++; ?> <html> <body> <form action="result.php" method="post"> <p> <b>2. Choose an option:</b><br> <input type="radio" name="q2" value="Increment"> Increment <br> <input type="radio" name="q2" value="NoIncrement"> No Increment<br> <input type="hidden" name="score" value="<? $_POST['score']; ?>"> <br> <input type="submit" value="Go to the next page"> </form> </body> </html> [/code] And finally, the result page (result.php): [code] <?php $score = $_POST['score']; $q2 = $_POST['q2']; if ($_POST['q2'] == 'Increment') $score++; ?> <html> <body> <?php echo '<b>The number of increments was ' . $score . '</b><br><br>'; ?> </body> </html> [/code] So, starting at q1.php, this little trio of pages asks whether the user wants to increment twice. Then on the third page, what I WANT it to do is display the number of times the user told it to increment. However, it doesn't; it says there was only one increment if the user chose that option on q2.php, and the variable $score is NULL if no increment is selected on q2. I know this is probably completely elementary, but I'm new at this. What am I doing wrong here?
