Register script error

I've been making a a login script and I'm working on the registration page. I'm not that great with php at all and I've just been teaching myself. I'm getting an error that I don't understand. Could somebody help?

Error:

Scriopt:

<?php

//get form info
$firstname=$_POST["firstname"];
$lastname=$_POST["lastname"];
$username=$_POST["username"];
$password=$_POST["password"];
$confirmpassword=$_POST["confirmpassword"];
$emailaddress=$_POST["emailaddress"];
$secretquestion=$_POST["secretquestion"];
$secretanswer=$_POST["secretanswer"];

//make variables some encrypt
$cpass = md5($password);
$cconfirmpass = md5($confirmpassword);
$cuser = md5($username);
$csecretanswer = md5($secretanswer);
$file = "users/" . $username . ".php";
$data = "<?php $cpass=" . $cpass . "; $cuser=" . $cuser . "; $firstname=" . $firstname . "; $lastname=" . $lastname . "; $secretquestion=" . $secretquestion . "; $csecretanswer=" . $csecretanswer . " ?>";

//make sure all info is ok
if ($password!=$confirmpassword)
	{
	echo 'Your passwords do not match. <A HREF="javascript:history.go(-1)">Try Again</A><br>'; exit(0);
	}

elseif (file_exists($file))
	{
	echo 'Username is in use. <A HREF="javascript:history.go(-1)">Try Again</A><br>'; exit(0);
	}

else
	{
	//make users file and redirect
	$handle = fopen($file, 'w');
	fwrite($handle, $data);
	fclose($handle);
	head ( 'location: index.htm' );
	}


?>

PHP:

Thanks in advance

 

head ( 'location: index.htm' );

should be

header ( 'location: index.htm' );

also why are you md5 hashing the username?

 

^ What he said, but also you might want to consider strtolower() when hashing things like a secret question, it's annoying when the answer is something like 'Digital point' and you're guessing 'Digital Point', also consider using a salt when making a password hash
