No as the error tells you, the header command must be the first instruction returned to the browser. The "header location" command redirects the users browser to the specified address in the arguments, and appears in the html head section.
More info on the header command is available here: http://uk.php.net/manual/en/function.header.php
To achieve the effect you are after you could use frames....

crs992,
headers must be changed and sent before sending any output (with echo or any other method).

| You can use ob_start(); at the top of your code instead of having the header first. |
