Solved: Member registration [Email won't connect to database]

Basically, I have a registration form with 3 text fields. Username, Password and Email.

The username and password appear in my database when signing up but the email is refusing to.
I have two files, reg.php and regcheck.php.

Here is my code:

reg.php

<?php
require_once 'database.php';
?>
<body>
<form method="post" action="regcheck.php" name="register">
  <br>
<label for="username">Username: </label>
<br>
<input id="username" class="input_field" type="text" onmouseout="if(this.value==''){this.value='Username...';}" onclick="javascript:void(0);if(this.value=='Username...'){this.value='';}" maxlength="150" value="Username..." size="35" name="user">
<br>
<br>
<label for="password">Password: </label>
<br>
<input id="password" class="input_field" type="password" onmouseout="if(this.value==''){this.value='Password...';}" onclick="javascript:void(0);if(this.value=='Password...'){this.value='';}" maxlength="100" value="Password..." size="35" name="pass">
<br>
<br>
<label for="email">Email: </label>
<br>
<input id="email" class="input_field" type="email" onmouseout="if(this.value==''){this.value='Email...';}" onclick="javascript:void(0);if(this.value=='Email...'){this.value='';}" maxlength="100" value="Email..." size="35" name="email">
<br />
<br />
<input id="search_btn" type="submit" value="Continue" >
<b>I agree to the Terms &amp; Conditions.</b>
<br>
</form>

Any help would be appreciated, I can't seem to find any errors. Maybe I'm missing something...
Thanks
