	Dynamic Officeselector
	
	made by Axxius
	last modified:
	    20030509 by Jeroen Zomer  - added posibility for HQs and 'Central Country pages'

	NOTE: add offices at the end of this file!

	USAGE:
	
	add the following line to your headsection: (mind the path!)
	<script type="text/javascript" src="officeselector.js"></script>

	build an officeselector in the following way: (again: mind the paths and filenames)
	
	<div class="contentBody">
	<!-- officeSelector -->
	<form name="officeSelectorForm" action="../content/offices/index.html" method="get">
		<select name="officeSelector" onchange="selectOffice()" class="flat">
			<option value="" selected="selected">select an office</option>
		</select>
		<script type="text/JavaScript">buildOfficeSelector('../offices/');</script>
		<noscript>
			<input type="submit" name="goButton" value="Go" />
			<a href="/content/offices/index.html">select from list</a>
  		</noscript>
	</form>
	<!-- /officeSelector -->
	</div>
	
	the function buildOfficeSelector() has an option path to the directory of files
