flash as2 sendAndLoad works only once

Hm, it seams that I was wrong. Don't know what is happening. Just now I have entered unused username and the data was stored in database. But _root.body.stranice.regform.gotoAndStop(3); didn't run so I have pressed send button once again and then there was an error (checklog = 2)  saying that username exists. So it means that the server get hit again. But when I changed username again into one unused it stil gives me the same error, like he remembered it and won't refresh, but delete myVars won't work.

I have changed a function. Maybe I can explain better now what is happening.

In php I have something like this:
$retval = $session->register($_POST['username'], $_POST['password'], $_POST['email'], ... etc
 if($retval == 0){
         $_SESSION['regsuccess'] = true;
         print "situation=You are registrated&checklog=1";
      }
      /* Error found with form */
      else if($retval == 1){
         $_SESSION['value_array'] = $_POST;
         $_SESSION['error_array'] = $form->getErrorArray();
             $usernameerror=$form->error("username");
             $emailerror=$form->error("email");
             $passworderror=$form->error("password");
             
             print "situation=Registration failed. ".$usernameerror." ". $emailerror." ". $passworderror.".&checklog=2";
             
      }
      /* Registration attempt failed */
      else if($retval == 2){
         $_SESSION['regsuccess'] = false;
         print "situation=Registration failed.&checklog=3";
      }

on (release, releaseOutside) {
		var result_lv:LoadVars = new LoadVars();
		var send_lv:LoadVars = new LoadVars();
		
		result_lv.onLoad = function(success:Boolean) {
			if (success) {
				trace("success");
				trace(result_lv);
				_root.body.stranice.regform.situations.html = true;
				_root.body.stranice.regform.situations.htmlText = result_lv.situation;
				if (result_lv.checklog == 1) {
					_root.body.stranice.regform.gotoAndStop(3);
				}
				if (result_lv.checklog == 2) {
 
					_root.body.stranice.regform.gotoAndStop(1);
				}
				if (result_lv.checklog == 3) {
					_root.body.stranice.regform.gotoAndStop(1);
				}
			} else {
				trace("failed");
				_root.body.stranice.regform.situations.htmlText = "Error connecting to server.";
			}
		};
		
		send_lv.adduser = 1;
		send_lv.status = "user";
		send_lv.username = _root.body.stranice.regform.username.text;
		send_lv.password = _root.body.stranice.regform.password.text;
		send_lv.name = _root.body.stranice.regform.name.text;
		send_lv.email = _root.body.stranice.regform.email.text;
 
		send_lv.sendAndLoad("userprocess.php?ck="+new Date().getTime(),result_lv,"POST");
 
}

When i submit form in flash with unused username everything is ok, data is passed into database and I get back in flash "You are registrated".
But if I submit a form with used username, I get back in flash "Registration failed. Username allready in use." (that is ok) but if I change username into one unused and press send button again there is still the same error "Registration failed. Username allready in use.".
Also if I delete @ mark from email in this same form and press send button once more I get more info about errors: "Registration failed. Username allready in use. Email is not correct."
But if I put @ mark back again and press send button again error info is stil there: "Registration failed. Username allready in use. Email is not correct." although now we have correct email and unused username in the form.

When I use this form on my local comp form fla file -> test movie, if I submit used username and get info about errors even when i close the window and start test movie again there is the same error. Only if I delete temporary internet files with offline contents and start movie again there is no errors.
So it's probably the flash that is caching this vars? How can I empty this cache?

on (press) {
      delete result_lv;
      delete send_lv;
}

Just to inform you that this is not working. Still gives the errors. Hoppe that someone will help me soon. I'm talking to myself here :)

I have tried to put  ob_start(); in PHP but it also didn't refresh the data.

Finaly I made it. I used unset() in PHP for variables $retval and $form->errors.

Glad to see that you've got the solution...  ;)

No, I don't need the point, but I just want to point out that it's Sunday today...  So things are quite slow...  You've got to consider that as well...  ;)
