[ic] use the tag in the perl function

[Xiaowen Wu]

I'm new to the minivend, and I have a very simple question, I want to add
the shipping handling fee to the totol_cost, so I think of adding 
something in the checkout.html like the followings:

handling: 
	<perl transaction> 
	$name = $Values->{name};
	$handling = $Tag->total_cost($name, 0);
	return $handling;
	</perl>

but it's not working, did I do something wrong. You help is very
appreciated. Thanks in advanced.
