mail Flash/PHP doesnt work...

Hi guys, im trying to make another mailer code using flash and php[, for a
contact us page on a site im working on..
The code i was using before used to work great, but now it doesnt work anymore
and i have no idea why.. I am using it on a different server, but the server
accepts php...

anyway, i was soo frustrated that it doesnt work, i went ahead and made a new
one... but this one doesnt work either... I need some help from you guys...

I will kick my self sooo hard if it's something simple that im forgetting...

heres the PHP code:

<?php

$name=$_POST['name'];
$email=$_POST['email'];
$number=$_POST['number'];
$subject = 'Comments From WebSite';
$message=$_POST['message'];

$name=trim($name);
$email=trim($email);
$number=trim($number);
$subject=StripSlashes($subject);
$message=StripSlashes($message);


$toaddress='seul_kof@yahoo.com';



mail($toaddress,$subject,$message,"From: $name <$email>");


$name='';
$email='';
$number='';
$subject='';
$message='';
echo "passed";

?>
