My people, I greet una.
Please, am trying out for the first time to process a Form with php. Somhow, the Form seems to work and even show me the 'thankyou.html' page after I submit but I've been waiting for the form contents (slept and woke up) and it has refused to come reach the email address I directed it to. I've change the email and tried and its still hanging out there in space. So please can somebody graciously take a look at my codes and show me my short-sightedness.

Here's the HTML for the form.

<script src="js/functions.js"></script>
<form method="post" action="sendmail.php" onSubmit="return validateForm(Array('FirstName', 'LastName', 'Email', 'WorkPhone'), this);" name="contact" id="contact">
