PHP mail script not sending to my email - php

Question

i have setup a form than when pressed the image submit button it sends the filled form to the buisness email.
Here is the script i have used for php linked from my html.
<?php
if(isset($_POST['submit'])) {
$emailbody = 'First Name = '.$_POST['Name']."\n"
.'Surname = '.$_POST['SName']."\n"
.'Email = '.$_POST['email']."\n"
.'Contact Number = '.$_POST['tel_no']."\n"
.'Adress Line 1 = '.$_POST['address_line_1']."\n"
.'Adress Line 2 = '.$_POST['address_line_2']."\n"
.'Town/City = '.$_POST['town_city']."\n"
.'County = '.$_POST['county']."\n"
.'Post Code = '.$_POST['Post_code']."\n"
.'Newsletter = '.$_POST['newsletter']."\n"
.'Events = '.$_POST['events']."\n"
mail('My email#gmail.com', 'Order Form', $emailbody);
} else {
header('location: Payment.html');
}
?>
The form on the html has been linked via a action. is there anything wrong with the script?
PS on pressing the image it is then forwarded to paypal payment page.
Cheers

Try changing
if(isset($_POST['submit']))
to
if(isset($_POST['SName']))
I think $_POST['submit'] doesn't work..
If this also fails then it means that the information isn't sent to your script.
In this case show us your html for the form used in the script.
EDIT
Using if(isset($_POST['submit'])) to not display echo when script is open is not working
EDIT AFTER HTML
in your javascript function called MM_validateForm
send your information using jquery POST to your mail script and remove the if clause checking if isset.
$.post("test.php", { name: "John", time: "2pm" } );
