Can't get php contact form to work - php

Question

I have a webpage that has two contact forms and the second one is working fine but I can't seem to get the first one to work. I am fairly new to php. Thanks in advance for the help. Here's the html:
<h3>Message Us</h3>
<form action="?" method="POST" onsubmit="return saveScrollPositions(this);">
<input type="hidden" name="scrollx" id="scrollx" value="0" />
<input type="hidden" name="scrolly" id="scrolly" value="0" />
<div id="msgbox1">
<label for="name2">Name:</label>
<input type="text" id="name2" name="name2" placeholder=" Required" />
<label for="email2">Email:</label>
<input type="text" id="email2" name="email2" placeholder=" Required" />
<label for="phone">Phone:</label>
<input type="text" id="phone" name="phone" placeholder="" />
<label for= "topic">Topic:</label>
<select id="topic" name="topic">
<option value="general">General</option>
<option value="stud">Property Price Enquiry</option>
<option value="sale">Bull Sale Enquiry</option>
</select>
</div><!--- msg box 1 -->
<div id="msgbox2">
<textarea id="message" name="message" rows="7" colums="25" placeholder="Your Message?"></textarea>
<p id="feedback2"><?php echo $feedback2; ?></p>
<input type="submit" value="Send Message" />
</div><!--- msg box 2 -->
</form><!--- end form -->
</div><!--- end message box -->
And here's the php:
<?php
$to2 = '418#hotmail.com'; $subject2 = 'MPG Website Enquiry';
$name2 = $_POST ['name2']; $email2 = $_POST ['email2']; $phone = $_POST ['phone']; $topic = $_POST ['topic']; $message = $_POST ['message'];
$body2 = <<<EMAIL
This is a message from $name2 Topic: $topic
Message: $message
From: $name2 Email: $email2 Phone: $phone
EMAIL;
$header2 = ' From: $email2';
if($_POST['submit']=='Send Message'){
if($name2 == '' || $email2 == '' || $message == ''){
$feedback2 = '*Please fill out all the fields';
}else {
mail($to2, $subject2, $body2, $header2);
$feedback2 = 'Thanks for the message. <br /> We will contact you soon!';
} } ?>
For the saveScrollPositions I use the following php and script:
<?php
$scrollx = 0;
$scrolly = 0;
if(!empty($_REQUEST['scrollx'])) {
$scrollx = $_REQUEST['scrollx'];
}
if(!empty($_REQUEST['scrolly'])) {
$scrolly = $_REQUEST['scrolly'];
}
?>
<script type="text/javascript">
window.scrollTo(<?php echo "$scrollx" ?>, <?php echo "$scrolly" ?>);
</script>

Answer 1

You have a mistake in your HTML part i.e.
<input type="submit" value="Send Message" />
add attribute name also in this input type like this-
<input type="submit" value="Send Message" name="submit" />
one thing more to correct in your php script is write-
$header2 = "From: ".$email2; instead of $header2 = ' From: $email2';
now try it.

Answer 2

What do you return in "saveScrollPositions" function? if you return false the form submit wont fire.
