Why isn't my php e-mail form working now?

[Conan O'Brien]

I added a php basic e-mail form on my website, and it worked a few times when I tested it... but now it doesn't seem to be working at all when I test it. When it did work, the e-mails were very slow coming to me. Why is that?

My host claims they support php.

Any ideas why this isn't working now?

Here's the code I used for the form:

<form method="POST" action="orderform.php">
Name
<br>
<input type="text" name="name" size="19"><br>
<p>
E-Mail
<br>
<input type="text" name="email" size="19"><br>
<p>
Name of Item
<br>
<input type="text" name="itemname" size="19"><br></textarea>
<p>
<input type="submit" value="Submit" name="submit">
</form>


And here's the file 'orderform.php':

<?php
if(isset($_POST['submit'])) {

$to = "(MY E-MAIL WAS HERE)";
$subject = "Order";
$name_field = $_POST['name'];
$email_field = $_POST['email'];
$itemname = $_POST['itemname'];

$body = "From: $name_field\n E-Mail: $email_field\n Item name:\n $itemname";

echo "Thank you for your order! You will be e-mailed your bill soon.";
mail($to, $subject, $body);


}
?>


NOTE: Recently I changed the php form so that the 'Submit' value is actually now 'submit,' so both cases match in the form and the php script. I was told it's case sensitive. However, that didn't seem to make a difference. I tried contacting the host, but they never answered. Can someone help me out, please?

Thank you all!!
