//how can i use javascript to read querystring?
var theQueryString= document.location.search


//how can i pass server side values from ASP to Javascript variables?
this is a state object that i use, it outputs a client side javascript
 with an array of variables passed from any server object.
use the scripts at the bottom on the client side to add to or modify the
server variables. these values are persisted in the query string between
pages....
check this out:

client scripts..........
<script language="javascript">

	function changeServerVars(varName,varValue)	{
