PHP Form

I have tried several solutions to this problem but to no avail. The form sends everything except the radio button value. I am providing the html form and php script below can you please let me know what I'm doing wrong? Also, I tried using header("Location:index.html"); but it doesn't work with this form. I placed the code after $send_contact=mail($to,$subject,$message,$header);. Am I not putting it in the right place? Your assistance will be greatly appreciated.

HTML CODE:

<table width="400" border="0" align="center" cellpadding="3" cellspacing="1">
<tr>
<td style="color:#FFF;"><strong>Contact Form </strong></td>
</tr>
</table>

<table width="400" border="0" align="center" cellpadding="0" cellspacing="1">
<tr>
<td><form name="form1" method="post" action="send_contact.php">
<table width="100%" border="0" cellspacing="1" cellpadding="3">
<tr>
<td style="color:#FFF;" width="16%">Name</td>
<td style="color:#FFF;" width="2%">:</td>
<td width="82%"><input name="name" type="text" id="name" size="50"></td>
</tr>
<tr>
<td style="color:#FFF;">Email</td>
<td style="color:#FFF;">:</td>
<td><input name="customer_mail" type="text" id="customer_mail" size="50"></td>
</tr>
<tr>
<td style="color:#FFF;">Subcribe</td>
<td style="color:#FFF;">:</td>
<td style="color:#FFF;"><input type="radio" name="subcribe" id="subcribe" value="Yes" checked="checked" /> Yes
<input type="radio" name="subcribe" id="subcribe" value="No" /> No</td>
</tr>
<tr>
<td style="color:#FFF;">Comments</td>
<td style="color:#FFF;" >:</td>
<td><textarea name="comments" cols="50" rows="4" id="comments"></textarea></td>
</tr>
<tr>
<td>&nbsp;</td>
<td>&nbsp;</td>
<td><input type="submit" name="Submit" value="Submit"> <input type="reset" name="Submit2" value="Reset"></td>
</tr>
</table>
</form>
</td>
</tr>
</table>

PHP CODE
<?php

// Details
$message="$comments";

// Subscription
$subcribe= $_POST['subcribe'];

// Mail of sender
$mail_from="$customer_mail";
// From
$header="from: $name <$mail_from>";

// Enter your email address
$to ='info@demetriusmcclain.com';

$send_contact=mail($to,$subject,$message,$header);

// Check, if message sent to your email
// display message "We've recived your information"
if($send_contact){
echo "Your information was successfully submitted. Return to";
}
else {
echo "ERROR";
}
