I may be onto a solution here, or maybe just a wild goose chase. I don't understand the code I'm looking at:
(from uc_shipping.module)
/**
* Implementation of hook_shipping_menu().
*/
function uc_shipping_menu($may_cache){
$items = array();
if (!$may_cache){
if (is_numeric(arg(3))){What is arg(3)? It doesn't return any value--other than ""--Nor does arg(5), both of which are found throughout this one function.
