Error when changing Header

[Nightsoft]

Im writing a simple mailform for a homepage and when it runs it and the mail is sent I wan't to changer the header to another page, that writes that the letter has been sent.
The problem is that when I try to change the Header it comes with the following error :

Warning: Cannot add header information - headers already sent by (output started at /home/

http://wwwsites/udd/tilmeld.php:1)

in /home/

http://wwwsites/udd/tilmeld.php

on line 40


I havn't change the header yet!!??
What's going on
My code looks (simplified) like this :

<?php

/* This is my line 1.*/

require "menu.php";

$content = "";
$error = "";

if ($ditnavn){
$mailrecepient = &quot;$modtnavn <$modtmail>&quot;;
$mailsubject = &quot;Tilmelding til \&quot;$forkortelse\&quot;&quot;;
$mailbody = &quot; $ditnavn har tilmeldt sig $betegnelse
$mailfrom = &quot;From: $ditnavn <$dinemail>\r\nReply-To: $dinemail\r\nReturn-Path: $dinemail&quot;;

/* some kode here (Simplified) */

mail($mailrecepient, $mailsubject, $mailbody, $mailfrom);

/* This is where it won't do it. My line 40*/

header("Location: [URL unfurl="true"]http://www2.spejdernet.dk/udd/emailsendt.php?modtnavn=$modtnavn");[/URL]
	exit;
}
?>

Why won't it change it?

Make sure that there is NO white space/free blank lines after the ending ?> php tag, that will cause the problem.

Hi Chris!

It worked. But then i got another error about the same, just in my line 9. In my line 9 i had one echo.
So i removed it and it worked.
My thought are that when i did a echo, it makes a page and automaticly makes a header info.
And header info on one page apparently can't be changed when it is loaded.

A'm I right.? Machine code Rocks

Yes, if you intend to use Header() you cannot echo any output before it. Regards,
