Internal link in javascript

[wxdqz]

I'm trying to get a dropdown box to act as an internal link selector...
Here is my code :

<form>
<select name="menu">
<option value=http://www.webdeveloper.com/forum/archive/index.php/"Doc"> Doc</option>
<option value="Flash"> Flash</option>
</select>
<input name="link to" type="button">
</form>

<br><br><br><br><br><br>
<a name="Documents">Doc section</a>
<br><br><br><br><br><br>
<a name="Flash">Flash section</a>

I'd like to select my destination inside the page with the dropdown menu and the button...How can i get this to work ?
Thank you
