HTML/CSS/PHP contact form is sending blank fields - php

Question

I'm by no means a web designer/coder, but I have enough general knowledge to get my website going. Just a simple portfolio website.
I'm having some problems with my contact form though. It's strictly CSS, HTML and PHP but when I put in the information (name, email and message) to test it, it sends me an email with those field headings, but no content. For example, the email displays as;
Name:
Email:
Message:
Even when filled out with information.
I have a feeling it's something small and a stupid error, so any help is greatly appreciated!
HTML
<div id="contact-area">
<form method="post" action="contactengine.php">
<input type="text" name="Name" id="Name" placeholder="Name"/>
<input type="text" name="Email" id="Email" placeholder="Email"/>
</form>
</div>
<div id="contact-area2">
<form method="post" action="contactengine.php">
<textarea name="Message" placeholder="Message" rows="20" cols="20" id="Message"></textarea>
</form>
<div id="submit-button">
<form method="post" action="contactengine.php">
<input type="submit" name="submit" value="SUBMIT" class="submit-button" />
</form>
</div>
</div>
PHP
<?php
$EmailFrom = "contact#brettlair.ca";
$EmailTo = "contact#brettlair.ca";
$Subject = "Contact Form";
$Name = Trim(stripslashes($_POST['Name']));
$Email = Trim(stripslashes($_POST['Email']));
$Message = Trim(stripslashes($_POST['Message']));
// validation
$validationOK=true;
if (!$validationOK) {
print "<meta http-equiv=\"refresh\" content=\"0;URL=index.htm\">";
exit;
}
// prepare email body text
$Body = "";
$Body .= "Name: ";
$Body .= $Name;
$Body .= "\n";
$Body .= "Email: ";
$Body .= $Email;
$Body .= "\n";
$Body .= "Message: ";
$Body .= $Message;
$Body .= "\n";
// send email
$success = mail($EmailTo, $Subject, $Body, "From: <$EmailFrom>");
// redirect to success page
if ($success){
print "<meta http-equiv=\"refresh\" content=\"0;URL=index.html\">";
}
else{
print "<meta http-equiv=\"refresh\" content=\"0;URL=index.htm\">";
}
?>

Answer 1

You have your form fields in one form, and the submit button in another. They need to be in the same form.
<form method="post" action="contactengine.php">
<input type="text" name="Name" id="Name" placeholder="Name"/>
<input type="text" name="Email" id="Email" placeholder="Email"/>
</div>
<div id="contact-area2">
<textarea name="Message" placeholder="Message" rows="20" cols="20" id="Message"></textarea>
<div id="submit-button">
<input type="submit" name="submit" value="SUBMIT" class="submit-button" />
</form>

Answer 2

$Name = Trim(stripslashes($_POST['Name']));
There is no Trim function, should be trim (lowercase).
