I Can't Get This Contact Form To Work!!! AGHH!!

Ok, I have a Contact form with four different fields to be submitted. However, when I use the form.. when people click "Submit" it goes through and even goes to the follow up page but it will not send e-mails and this is infuriating. If anyone sees any errors or something I have overlooked.. please let me know.

Here is the code for the HTML page (Where the contact form is)

<div id="contact-wrap">     <form action="contact-sent.php" method="post" name="contact" enctype="text/plain">
     	<div id="contact-reason">
        <select name="reason" style='width:150px;height:20px;'>
<option value="question">I have a question</option>
<option value="comment">I have a comment/bug/glitch report</option>
<option value="suggestion">I have a suggestion</option>
<option value="other">Other</option>
</select>
        </div>
     	<div id="contact-first-name"><input type="text" name="firstname" style='width:100px;height:18px;border:hidden;background-image:url(images/contact-100-width.png);opacity:0.6;filter:alpha(opacity=60);'/></div>
        <div id="contact-armory-link"><input type="text" name="armory" style='width:400px;height:18px;border:hidden;background-image:url(images/contact-400-width.png);opacity:0.6;filter:alpha(opacity=60);'/></div>
        <div id="contact-e-mail"><input type="text" name="e-mail" style='width:200px;height:18px;border:hidden;background-image:url(images/contact-200-width.png);opacity:0.6;filter:alpha(opacity=60);'/></div>
        <div id="contact-message"><textarea name="message" style='width:560px;height:133px;background-image:url(images/contact-message-area.png);opacity:0.6;filter:alpha(opacity=60);resize:none;'/></textarea></div>
        <div id="contact-submit"><input type="submit" value="Submit" style='width:150px;height:100px;border:hidden;background-image:url(images/contact-submit.png);opacity:0.6;filter:alpha(opacity=60);'/></div>
     </form>
     </div>

And here is the code for the PHP the contact-sent.php file
