            <td><? echo $answer[$i][$j]; ?></td>
<input type="submit" value="show results !"></center>



The way I would approach this is with AJAX. Make a front facing page with your HTML. Start with question 1 and send answer to an ajax.php (name can be anything) using jQuery (http://api.jquery.com/jquery.ajax/).

In ajax.php process the answer to the original question and send back HTML for the second question and answer options as ajax response. Use jQuery's html method (http://api.jquery.com/html/) to integrate the html into your page dynamically.

Rinse and repeat. When done, return HTML with results. You can pass some parameters back and forth to keep track of what question you are on, answer totals, etc - depending on what you need.
