Dynamic php page - option selected

[KevinBeyers]

Hi,

I wanted to make a dynamic php page. I want the user to choose an option you could select in an option box (html) and after that I wish that down the page some text would change. If I take option 1 -> text 1, option 2 -> text 2, ...
But this doesn't work, do I need a button or something to made my code running, and how do I have to use it on the same page?
Or is it possible to run it automaticly after a new choice?

Thanx, Kevin



My code:

<?php
/*
Template Name: template voor Ieder1Trainer #
*/
get_header(); 

$Tacktiek = "";

$Tacktiek1 = "3-5-2";
$Tacktiek2 = "3-4-3";
$Tacktiek3 = "4-5-1";
$Tacktiek4 = "4-4-2";
$Tacktiek5 = "4-3-3";
$Tacktiek6 = "5-4-1";
$Tacktiek7 = "5-3-2";

$aantalDef;
$aantalMid;
$aantalAtt;

?>

<div id="newsfeed">

    <div class="banderol">
        <div class="banderol_left"></div>
        <h1>Dynamic page</h1>
    </div>    

    <?php if(is_user_logged_in()) { 
        get_currentuserinfo();
        //echo 'Username: ' . $current_user->user_login . "\n";
        //echo 'User email: ' . $current_user->user_email . "\n";
    ?>

    <tr>
