[PHP] problem sending vars from Flash

hey there, i have a mail php script that i used and im trying to apply it to another project. everything is the same except the name of the php file (instead of mailform, its named ‘emailform.php’). I checked both files and when i upload to the server to test, i dont get any confirmation, email, nothing. here is my php script:

<?  

$adminaddress = "luv98ca80@yahoo.com"; 
$siteaddress ="http://www.avidgraphics.net"; 
$sitename = "Avid Graphics"; 

//No need to change anything below ... 
// Gets the date and time from your server
$date = date("m/d/Y H:i:s");

// Gets the IP Address
if ($REMOTE_ADDR == "") $ip = "no ip";
else $ip = getHostByAddr($REMOTE_ADDR);

// Gets the POST Headers - the Flash variables
$action = $HTTP_POST_VARS['action'] ;
$email = $HTTP_POST_VARS['email'] ;
$name = $HTTP_POST_VARS['name'] ;
$comments = $HTTP_POST_VARS['comments'] ;

//Process the form data!
// and send the information collected in the Flash form to Your nominated email address

if ($action == "send") {
	//
	mail ("$adminaddress","Info Request",
	"A visitor at $sitename has left the following information

	Name: $name 
	Email: $email

	The visitor commented:
	------------------------------
	$comments
	
	Logged Info :
	------------------------------
	Using: $HTTP_USER_AGENT
	Hostname: $ip
	IP address: $REMOTE_ADDR
	Date/Time:  $date","FROM:$adminaddress" ) ; 
	
	//This sends a confirmation to your visitor
	mail ("$email","Thank You for visiting $sitename", 
	"Hi $name,

	Thank you for your interest in $sitename!

	Cheers,
	$sitename
	$siteaddress","FROM:$adminaddress") ; 
	
	//Confirmation is sent back to the Flash form that the process is complete
	$sendresult = "Thank you. You will receive a confirmation email shortly.";
	$send_answer = "answer=";
	$send_answer .= rawurlencode($sendresult);
	echo $send_answer;
} //
