A little trouble with PHP mail

I have been working on how to have my contact page email me after it submits info to my data base. This is the only way I could get it to work at all is this good syntax or should I write it a different way. I had to close out what went to the data base and open another php area to get it to stop throwing an error. All help appreciated.

     <html>
              <head>
                <title>Processing form</title>
                
                <style>
                    h1   {color:#000080; font-size:35px}
                </style>
		              </head>
		             
		                 <?php
							$con = mysql_connect("localhost","######","#######");
							if (!$con)
							  {
							  die('Could not connect: ' . mysql_error());
							  }
							
							mysql_select_db("db", $con);
							
							$sql="INSERT INTO contact (id, first_name, last_name, address, city, state, zip, area, exchange, phone, email, contact, services, comments)
							VALUES
							('$_POST[id]','$_POST[first_name]','$_POST[last_name]','$_POST[address]','$_POST[city]','$_POST[state]','$_POST[zip]','$_POST[area]','$_POST[exchange]','$_POST[phone]','$_POST[email]','$_POST[contact]','$_POST[services]','$_POST[comments]')";
							
							if (!mysql_query($sql,$con))
							  {
							  die('Error: ' . mysql_error());
							  }
							echo "1 record added";
							
							mysql_close($con)
							
							?>
									
							<?php
									$to = "harts@hartsmachineservice.com";
									$subject = "Contact Page";
									$message = "John: Some one has filled and submitted your contact page";
									$from = "harts@hartsmachineservice.com";
					                $headers = "From: $from";
									mail($to,$subject,$message,$headers);
									echo "Mail Sent ";
						
						     ?>
							
							
						

		                  
				            <h1>Your information has been successfully submitted to Hart's Machine Service.<br />
				                 We will contact you as soon as possible.</h1> 
				             
				            </body>
				            </html>

Thank you very much that allowed me to put it all in one php statement or section. It is crazy how sometimes one little mistake can mess everything up. Thank you again.

You missed the semicolon after your mysql_close statement.
