Hello, I have Joomla 1.5 and Metamod pro.  Im trying to make 6 modules appear on the home page then disappear.  I tried this...

session_start();
/* set a different "instance name" for each module that you want to show only once */
$instance_name = "shown_module_1";
if (!isset($_SESSION[$instance_name]) ||
$_SESSION[$instance_name] == false) {
$_SESSION[$instance_name] = true;
/* customise "101" to your own module number.
  * This is the one that gets shown just once per session.
  */
return 147;
}
/* customise "102" to the module you want to display on the 2nd, 3rd... showing.
* You can leave out the following line entirely if you don't want to display
* a module after the first showing.
*/

I tried this to make the mods get seen once but it blocks out all the others and only show one. Any thoughts?


Also i was wondering is there a recipe to make mods show for about 5 minutes and then disappear?
Any help would be great. Thanks
