PHP in CS3 refreshes page?

on the submit button in a form in Flash CS3 I have this:

                  
on (press) { 
    
function doSubmit() 
{ 
userData = new LoadVars(); 
userData.fullName = fullName.text; 
userData.desiredPrice = desiredPrice.text; 
userData.acreage = acreage.text; 
userData.phone = phone.text; 
userData.altphone = altphone.text; 
userData.email = email.text; 
userData.chat = chat.text; 
userData.radioGroup = radioGroup.getValue(); 
userData.location1 = location1.text; 
userData.send("chad.php", "", "post"); 
} 
   doSubmit(); 
   gotoAndStop(2); 
    
} 

It works fine as far as the chad.php file. The thing is, this swf is placed on a page and instead of stopping on frame 2 (as above) the whole page leaves…as if it expects the chad.php to return a page.

This has never worked like this before. I use a basic email script to capture and send data and the flash file goes to the next frame and stops.

Now, it doesn’t and I’m wondering why? Very basic PHP:

 <? 
$name = $_POST['fullName']; 
$acreage = $_POST['acreage']; 
$radioGroup = $_POST['radioGroup']; 
$location1 = $_POST['location1']; 
$desiredPrice = $_POST['desiredPrice']; 
$phone = $_POST['phone']; 
$altphone = $_POST['altphone']; 
$email = $_POST['email']; 
$chat = $_POST['chat']; 
 
$message = "$radioGroup
"; 
$message .= "$name
"; 
$message .= "$phone
"; 
$message .= "$altphone
"; 
$message .= "$email
"; 
$message .= "$acreage
"; 
$message .= "$desiredPrice
"; 
$message .= "$location1
"; 
$message .= "$chat
"; 
 
$body = $message; 
 
mail('kelly@thumbslinger.com', 'latest chad', $body); 
?>  

So I’m trying to understand why a new page loads rather than just the Flash part going to the next frame.

The basics I’ve used is at http://www.fitmaven.com and [URL=“http://www.sapphiremonkey.com/”]www.sapphiremonkey.com where one can sign up for the newsletter. Small bit of Flash, upon submit, the mail is sent and it stops on frame 2.
