PHP: How to run a script, after a selection of an entry-form?

[Bernhard Rieder]

I created a form and the user can select from two countries.

[html]<form action="mein-script.php" method="get">
<tr>
<td class="br_td">Wo hast Du Deinen Wohnsitz?
<select class="br_select" name="land">
<option value="germany">Germany</option>
<option value="austria">Austria</option>
</select></td></tr>
<input class="br_button" type="submit" target="_blank" value="Klick + Resultat zeigen">[/html]


If you select Germany, the script germany.php should be rendered.

If you select Austria, the script austria.php should be rendered.


How to do that?
