Hi trying to create a list structure list "nvidia/ati" had before you select something in one list and then the second list updates with values based on you selection. It will not be drivers and static items tho.

So the purpose of this is to get a tree structure from members so the first list will be a list with all members im in first list to be parent to.

So if the first list is:
Tom
Jay
Markus

If i select Tom, i sould from a mysql query get all children to Tom, and so on in 5 levels.

Currently I have this bit of code:

<?php
require_once('auth.php');
require_once('config.php');

You are mixing javascript and php. This is not possible.

PHP is a server-side language where as javascript is client side. They cannot communicate with each other directly. Your best bet would be AJAX, which is the workaround to your problem.

Since your experience with web development is limited, trying to use AJAX might be a nightmare for you though.

This code works in firefox but not in IE and crome then I get these errors!

Warning: mysql_fetch_array() expects parameter 1 to be resource, null given in C:\wamp\www\NSE-Klient\my-team.php on line 180

regardless of your code, you need ajax. I would suggest something like jQuery and search for 'chaining select' or similar. It is quite straightforward though.

$('select').change(function() {
  doChanges($(this).attr("id"),$(this).val());
});

All select boxes are now linked to the js doChanges function which has 2 parameters: the id of the calling select widget and the changed value. Your doChanges should then pass on the data to a php script. The php script processes all the data and decides which select boxes to update. This info (box ids and option values) can be passed back to the doChanges script for updating. Personally I'd pass the info from php to js via JSON.

#EDIT
Just thought, you don't want your last select box to trigger a change as this will not have any effect on the hierarchy wiil it? Oh well, this only needs a small modification.
