Help with sessions/colour chaning please!

[benbox]

Hi,

I have the following code in a file being included onto every one of my pages.

<?
session_start() ;

if(!isset($colour)) {
$colour = "green" ;
}

if($colour=="green") {
$imgdir = "./images/green/" ;
$darkcolour = "#002409" ;
$pagebg = "#056340" ;
}

if($colour=="blue") {
$imgdir = "./images/blue/" ;
$darkcolour = "#061F2D" ;
$pagebg = "#0F4360" ;
}


session_register("colour") ;
?>

if I comment out the session_register - the site colour changes fine, but of course it doesnt remember the colour for when you next click on a link.

but when the session_register is there, the site won't change colour.

the links i have are <?=$PHP_SELF?>colour=blue and <?=$PHP_SELF?>colour=green

could anyone help be in telling me why this could be happening?

Thanks
Ben

Try

$session_start();

$colour = $_SESSION['colour'];

....
