Hi guys,y

Again I am in trouble, this time with PHP....

I am getting the following error on my browser:

Warning: Cannot modify header information - headers already sent by (output started at /home/site/public_html/index.php:5) in /home/site/public_html/getresult.inc on line 13

I checked out on Google, everywhere it says that there must be some extra spaces in the code. But I checked out there are no extra spaces.

The PHP file is containing the HTML code also.
<BODY vLink=#669900 aLink=#669900 link=#669900 background="bg.jpg" topMargin=0>
<?php include("getresult.inc");?>
<form ACTION.........

In getresult.nic, line 13 is having a header line:
header("Location: main.htm");

Can anyone help please.

Its Urgent!!!!
