Yes this is the case.

However, what you said brings up a point if interest.  The page that  
the link is bringing up contains the following:

	if ($_GET["iid"]=='') {
	$item_id = ($_SESSION["item_id"]);
	}
	else
	{
	$item_id = $_GET["iid"];
	}

This code determines if the user is getting there from the initial  
link and if so, sets the variable item_id to the value passed in the  
URL.
Again however, this was not returning errors when the link was  
hardcoded with a value in place of item_id.
