[chup]

I have the following code that work fine,

on (release) {
	cardno = 1234;
	random2 = Math.ceil(Math.random()*1000000);
	loadVariablesNum("view.php?reload="+random2, 0, "POST");
	gotoAndPlay(3);
}

but what if i wanan encode the "cardno" var behind an url, somthing like
http://www.demo.com/view.htm?cardno=1234

it doesn't work anymore. Any idea?
