PHP Contact Form

I have a PHP contact form. I want the email to go to the friends email. When I put a static email in such as sample@aol.com it sends the email, however; I need to have it be dymaic and send to whatever email is placed in the friends email field. I tried this and it doesn't send.

PHP Code:

---

// User settings
$to = $email;
$subject = "Bri Cooper"; 


---

the website is http://www.bricooper.net

Go to share and you will see the form pop up.

I have attached the PHP file as a text file.

Try to set a value for the friend's email as POST since you use it down in your send action...
$_POST["email"]

<label for='contact-email'>*Friends Email:</label>
<input type='text' id='contact-email' class='contact-input' name='email' tabindex='1002' value="<?php $_POST["email"] ?>" />";
