Form throwing error messages

When I submit my form, I get an the "You must write a message" echo from the PHP code, and I also get the error message from the ajax. I don't need the PHP echo messages because I have the ajax messages. Can't figure out the problem.

I would like to only use the ajax messages.

Here is the ajax:

Code:

---

$(function(){

$("#btnSend").click(function(){

$.ajax({type:'POST', url: './php/mailer.php', data:$('#frmContact').serialize(), success: function(response) {
$("#spanMessage").html('Please Wait...');


        if(parseInt(response)>1)
          {
                $("#spanMessage").html('<div class="alert alert-success"><button type="button" class="close" data-dismiss="alert">&times;</button><strong>Well done!</strong> Your message has been sent.</div>');
          }
          else{
                alert(response);
                $("#spanMessage").html('<div class="alert alert-error"><button type="button" class="close" data-dismiss="alert">&times;</button><strong>Error! </strong> Somthing Wrong</div>');
          }
         
               
}});


});

Here is the PHP:

PHP Code:

---

<?php session_start();
if(isset($_POST['Submit'])) {
$youremail = 'wjordan1987@gmail.com';
$fromsubject = 'Test Email';
$txtName = $_POST['txtName'];
$txtEmail = $_POST['txtEmail'];
$txtSubject = $_POST['txtSubject']; 
$txtText = $_POST['txtText']; 
$to = $youremail; 
$mailsubject = 'Masage recived from'.$fromsubject.' Contact Page';
$body = $fromsubject.'

The person that contacted you is  '.$txtName.'
 E-mail: '.$txtEmail.'

 Message: 
 '.$txtText.'

|---------END MESSAGE----------|'; 
echo "Thank you fo your feedback."; 
                            mail($to, $subject, $body);
 } else { 
echo "You must write a message."; 
}
?>

Here is the HTML form:

HTML Code:

---

<form action="" method="post" id="frmContact">
<h5>Whats your Name?</h5>
<input name="txtName" type="text" class="txbx" value="Name" /><br />
<h5>Whats your Email?</h5>
<input name="txtEmail" type="text" class="txbx" value="Email" /><br />
<h5>Email Subject?</h5>
<input name="txtSubject" type="text" class="txbx" value="Subject" /><br />
<div class="erabox">
<h5>Message to us</h5>
<textarea name="txtText" cols="" rows="" class="txbx era" value="Message" ></textarea><br />
<input name="Submit" type="button" class="sendbtn" value="Send Message" align="left" id="btnSend"/>
</form>

In the PHP code, just comment the line

Code:

---

echo "You must write a message.";

---

.

By commenting, you simply put "//" at the beginning of the line.

Or, you can delete the line alltogether.

I dont think the commenting the line makes any difference? error is still poping.

try to change the line

Code:

---

<input name="Submit" type="button" class="sendbtn" value="Send Message" align="left" id="btnSend"/>

---

to

Code:

---

<input name="Submit" type="submit" class="sendbtn" value="Send Message" align="left" id="btnSend"/>

---

I have tested the code and it worked for me :)
And one more thing: why don't you use SMTP Mailer?...it's more reliable and a bit faster

the code is live at http://ssservices.co/contact.html it is not working for me... can you suggest appropriate.
