Converting Send to SendAndLoad

programming flash
1 

var listener:Object = new Object();
listener.onComplete = function(target:MovieClip, load_var:LoadVars) {
    load_var.send("myname.php", "", "POST");
}

This works fine, but it redirects the SWF to a the page.
So I looked it up, and it said to use sendAndLoad.


var listener:Object = new Object();
listener.onComplete = function(target:MovieClip, load_var:LoadVars) {
    load_var.sendAndLoad("myname.php", "", "POST");
}

I also tried


load_var.sendAndLoad("myname.php", "load_var", "POST");

But it doesn’t work, and yes I tried it in the browser. Any ideas?
