Pass sendAndLoad var to _root

Question

I have an app that has been getting the username of a user
into a simpleConnect for a chat application by passing it in via
the embed params, but this creates a security issue and would like
to pass it in using sendAndLoad.
Currently the username value is set simply by using: var
username=_root.username, because it's passed in via a php page with
that variable in the embed params. Like this:
<embed src="member.swf?username=<?php echo
$row_getMemberData['username']; ?>
The ID in this example is hardcoded but would be passed in
the same way that I'm currently passing in the username:
member_id = 10762;
mid = _root.member_id;
var send:LoadVars = new LoadVars;
var receive:LoadVars = new LoadVars;
send.mid = mid;
receive.onLoad = function(){
_root.username=this.username;
send.sendAndLoad("
http://urltomyphppage.php",receive,"POST");
trace(username);
stop();
That trace comes up undefined. I can trace it from within the
function, but I need to make it available to the main timeline so
the simpleConnect can pick it up....
As always any help at all would be greatly appreciated!!!

I am sorry, but I fail to see what it is that you are trying to do
<div id="list" spry:region="dsContratto">
          <!--- region ---> 
          <tr spry:repeat="pv" spry:even="even" spry:odd="odd"> 
              <a href="javascript:open({contratto_id},'sost')">OpenModal</a> 
          </tr> 
</div>
I can see that this opens a separate window, but how does the following relate to the above?
function open(id, action) { 
    open modal and linked-region
function funcObserverLinkedRegion(notificationState, notifier, data) { 
    how a can get value of "action" var?
Spry.Data.Region.addObserver("detail", funcObserverLinkedRegion);
