[Christian Ruhland]

Hi,

i have a little Problem with Gantry, Joomla and webisco (shopsystem).

Webisco want to load a sssion start in my code.  

<?php

session_start();

require_once('webisco.inc.php');

initWebisco('demo');

showWebiscoWidget('demo', 'copyright');

?>

Where must i copy this code? In the tmplate index.php or in another document.

I want to show the shiop only in a menu who named: shop.
