Sendmail problem

1

I have this as the form:


<form action="sendmail.php" method="post" name="subscribeForm" 
id="subscribeForm">
<div style="padding:15;color:717171"	 class="ver10">

Name:&nbsp;&nbsp;<input type="text" name="name" 
size="16">&nbsp;&nbsp;&nbsp;

Subscribe&nbsp;&nbsp;&nbsp;&nbsp;<input type="radio" value="subscribe" 
checked name="subscribe">
<br><br>

E-mail: &nbsp;<input type="text" name="email" 
size="16">&nbsp;&nbsp;&nbsp;

Unsubscribe<input type="radio" name="subscribe" value="unsubscribe">
<br><br>

<div align="center"><input type="image" border="0" name="submitImage" 
value="submit" src="images/submit.gif"></div>
<br><br> 
Sign up for news and updates! </div>
</form>

THIS IS THE CODE IN THE SENDMAIL.PHP file:


	$name = $_REQUEST['name'];
	$email = $_REQUEST['email'];
	
	if (!empty($subscribe) AND !empty($unsubscribe))
	{
	echo("Please select either Subscribe or Unsubscribe. You cannot select 
both at the same time.");
	}
	
	if(empty($name))
	{
	echo("Please go back and enter your name.");
	die();
	}
	
	if(empty($email))
	{
	echo("Please go back and enter your email.");
	die();
	}
	
	$subs = $_REQUEST['subscribe'];
	$dataSent = 'Name: ' . $name . '  --- Email: ' . $email . '  --- 
Request: ' . $subs;
  mail( "chafasite@yahoo.com", "Betheltrips.com Subscribe-Unsubscribe 
Contact Form", $dataSent, "From: $name" );
  header( "Location: 
http://www.betheltrips.com/wFlash/confirmation.php" );

THIS IS THE ERROR I GET ON THE BROWSER:

Warning: mail(): “sendmail_from” not set in php.ini or custom “From:”
header missing in C:\Apache2\htdocs\betheltrips\wFlash\sendmail.php on
line 24

Warning: Cannot modify header information - headers already sent by
(output started at C:\Apache2\htdocs\betheltrips\wFlash\sendmail.php:24)
in C:\Apache2\htdocs\betheltrips\wFlash\sendmail.php on line 25

What am I doing wrong? The From in the header is set on the script.
Please help. [hair]

Thanks in advance,
