PHP Mailer question

1

Hey Guys, I’m having a hard time with a simple code. I got this from a website and I only eddited what I needed to. But wehn I use it, it gives me this result

Warning: Invalid argument supplied for foreach() in /home/u2xs/public_html/magnum/php/mailer.php on line 11

The Entire Code is

<?php
if(isset($_POST[‘submit’])) {

$to = "sergio@u2xs.com"; 
$subject = "A question from $name at MT.com";
$name = $_POST['name'];
$company = $_POST['company'];
$eMail = $_POST['eMail'];
$telephone = $_POST['telephone'];
$message = $_POST['message'];
foreach($_POST['check'] as $value) {
    $check_msg .= "Checked: $value

";
}

$body = "    Name: $name
E-Mail: $eMail
Company: $company
Telephone: $telephone
Message: $message";

echo "&lt;HTML&gt;&lt;body bgcolor=0C2776 text=white&gt;&lt;font size=7&gt;Thank you&lt;/font&gt;&lt;/body&lt;/html&gt;";
mail($to, $subject, $body);

} else {
echo “blarg!”;
}
?>

The part I believe has a mistake is this one…

foreach($_POST['check'] as $value) {
    $check_msg .= "Checked: $value

";
}

Any thoughts??? Thanks
