Cannot get parsed code to work!!!

[kau]

Ok I have a simple script I want to run in my header like this:

require("config.inc.php3");
require("view.inc.php3");
require("acl.inc.php3");
view("468x60");

It will display a banner. However PHP no matter if it's in PHP tags or not will not parse in the Header box only in the PHP parsed code. However if I put that code in that box the banner just appears at the top of the screen and not where I want it.

How do I put PHP in my Header?
